FixMbr?

WindowsXP SP 3

Just a couple of minutes ago I attempted to use fixmbr command from a

Recovery Console cd(a burned cd image file of recovery console) everything

went fine. I saw the command prompt window flash and it even gave me the

warning aboutm proceeding.

But whrn I rebooted grub(linux bootloader) was still there. There is nothing

wrong with my computer mind you, I can boot in to either system. The only

reason I am doing this is to make ntldr my bootloader. Why didn't fixmbr work?

Maybe you should boot off a real Recovery Console instead of a burned CD

image of one.

I just thought the cd would be better. I don't have an xp cd because my

laptop came with Recovery cds and no Recovery Console, So that is why I use

alternate methods to obtain it. Should I go ahead and use my boo.ini entry

and see if it works?

I also have a Win98 bootdisk. form bootdisc.com which you told me about.What

would you do?

I would use the Win98 boot disk. Its "fdisk /mbr" will work very nicely for

your WinXP installation, regardless of the file system you use.

Thanks for trying to help me out Pegasus but it doesn't matter now. My

laptop does

not support LBA(logical Block Addressing). When I set out to dualboot Mw

Windows xp install

and Ubuntu I read about LBA limitations so I knew to avoid any problems make

sure to install Ubuntu

on my second partition which is well inside the 8.5gb limit. But it was

several days later before

I actually whetn ahead and installed Ubuntu. And I changed it's location to

the 4th partition on my

drive(brain fart) which is well outside the LBA limits. It is too much

effort to change things now

So I will keep using Grub.

Re: FixMbr?

 

It's extremely rare to find one that doesn't support LBA. Some HP laptops

(530?) default to Large (bit-shift) access, and the issue here is that you

cannot change this to LBA without a complete reload of the disk. Why they do

this I don't know as LBA is the universal standard these days,

 

Though, I find that Ubuntu's insistence on modifying the MBR is as

undesirable as Vista's insistence on doing the same thing. There is in fact

no need for an OS to modify the MBR, and most other distros offer the option

of not doing so.

Do you mean that you made a bootable cd image of Recovery Console

that loads before the processes of the operating system? The option

in boot.ini gives you a choice to load RC before Windows XP loads.

 

Even if you did make a bootable RC image, you don't know that it is

exactly equivalent in terms of files and settings as using cmdcons

installed on the disk. Remember this observation from AumHa,

 

"The only question many experienced hands with Windows is why it was

not included by default. The answer is in most cases was because the

OEMs did not want to pay a modest licensing fee to include it."

 

Bill Castner is not going to provide a method to circumvent MS policy

because he is a MS-MVP. Since Bill did not mention the possibility of

of writing this to a bootable RC cd, there is probably not a straight-

forward way of writing your C:\cmdcons files to a bootable functional

RC cd. If there is such a method, legitimate websites and MS-MVPs are

not going to say how to do this in order to circumvent MS policy. It

is possible for MS to approve the C:\cmdcons method and not approve

a bootable RC method and it does little good to speculate on why. It

is a very remote possibility that Bill Castner didn't mention the

possibility of creating a bootable RC cd because he didn't think of it.

 

The other things Bill mentioned to improve the flexibility of RC

with registry edits, OTOH, are likely to prove to be very valuable

for reasons that people who are not used to reading instructions

and following those instructions precisely and exactly can imagine.

Of course there are people who just have to find out the hard way

for why they should heed the advice to make backups including the

registry and the MBR.

 

ManyBeers wrote: > "There is nothing wrong with my computer mind

you, I can boot in to either system."

 

SH: So have you backed up this functioning MBR? So that in case

using fixmbr or fdisk /mbr doesn't work, and you wind up in the

position of being unable to boot to either OS, you can restore

an MBR that is known to allow you to boot to either system. This

actually happened to me when I was experimenting with both fixboot

and fixmbr and BootIt NG. You impress me as a dabbler,

 

So it is better to be safe than sorry, an ounce of prevention...etc

I think you can copy/tar the entire contents of the /boot partition

(4th) over to your second partition and then update fstab to point

to the new partition. If /dev/hda1 is your Windows partition then

/dev/hda2 will be your second partition which you can populate with

your /boot files. This idea should be checked over on a Ubuntu forum.

Well cmdcoms on my disk was dowmloaded from links in the Aumha how-to

So neither may be equivalent. My laptop has no Recovery Console natively

so when I saw that Aumha how-to it sounded like a good idea, even though

I had no idea how to use it. I do now...somewhat.

I don't know how to back up my MBR. I assumed if something went wrong I would

boot into my System Rescue CD and make Ubuntu the bootable partition again.,

which is relatively easy to do. It will restore Grub to the MBR. Hell ,I

used the SRCD to retrieve the GRUB stage 1 file and mounted a fat32 drive to

copy the file to(and I have never mounted a drive in my life...unmounted it

too). Mounting was done through a Terminal window in SRCD's graphic

environment and I unmounted the drive using Gparted another graphic tool. I

didn't think I could get in too much trouble so long as I could boot the SRCD.

You just need to make sure that your system doesn't break if the disk

signature changes (fdisk /mbr will make that change). Or at least, you

know how to recover from it.

Yes, I think it is a great idea, even if you have an install disk.

The reason to load Ubuntu from the XP boot.ini was to ensure that

RC boot option (from C:\cmdcons) was maintained. When you booted up

you would get choices like boot from

 

Windows XP or

Recovery Console or

Ubuntu

 

I wasn't sure that if you used grub and you picked Windows XP that

it would present you with screen you started with before Ubuntu.

 

Windows XP

Recovery Console

 

I thought there was a chance that you would lose the RC option.

Now that you have grub installed and can find out, do you still

have the RC option when you choose Windows XP or whatever you

called the XP boot label? Does it offer the boot.ini choices of

Windows XP and Recovery Console? After you installed C:\cmdcons

did you follow the step where it had you write the Recovery

Console as a boot option to boot.ini? Or did you only try

creating a cmdcons cd. Here is a link to a grub tutorial,

I don't understand this. I thought you were going to make the

first sector of the Ubuntu partition bootable so that the MBR

wouldn't be written to so that your RC option would be preserved.

Do you have both options appearing in your boot.ini

 

default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS

[operating systems]

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP

Professional" /noexecute=optin /fastdetect

C:\CMDCONS\BOOTSECT.DAT="Microsoft Windows Recovery Console" /cmdcons

 

Since you are using Grub, and it should offer you the choice

of booting Windows XP, when you select the Windows XP option,

does it also offer you the choice of the Recovery Console bootup.

Yes I do. And mt Recovery Console is stikk available even thoughGrub is the

bootloader. Whrn I make my menu selection in Grub it doesn't boot Windows it

boots

Windows Boot.ini and I can then select Recovery Console. In fact when my XP

wakes up from hibernation it displays Grubs boot menu(which I modified to

make XP the default after 10 seconds) , waits for ten seconds then displays

XP's boot menu

waits 5 seconds and then brings up my desktop.

Yes it does so via XP's boot.ini .

Re: FixMbr?

 

There is no need to tar and untar. In principle you can transfer a Linux

install to another disk/location using plain ordinary cp with the -a switch,

it works much like xcopy did for win98. This should be done from a live CD

distro. -Linux has no equivalent of shadow copy so you cannot guarantee a

good copy from a running OS.

 

You then need to adjust fstab and the bootloader. fstab is easy, the

bootloader not always so. As I use lilo you would be better to ask a grub

expert here.

 

Other point to note is that you MUST transfer the permissions (which cp -a

does) XP (or even Vista) will work without permissions, Linux will not.

 

"I think you can copy/tar the entire contents of the /boot partition

(4th) over to your second partition and then update fstab to point

to the new partition. If /dev/hda1 is your Windows partition then

/dev/hda2 will be your second partition which you can populate with

your /boot files. This idea should be checked over on a Ubuntu forum. "

Good. I guess it felt sort of heroic mounting and unmounting

partitions, not at all your usual Windows fare.

Oh yeah, lots of fun.I do know one thing-the only reason ntldr woul not boot

Linux

is because my BIOS does not support LBA(which I verified through Sony support)

GRUB does implement it.and can boot OS's located beyond 8.5 gb's. In fact the

Gparted partitioning tool clearly showed when Ubuntu was flagged to boot... my

storage drive which was located about 6.5 gb's in had an LBA flag on it. When

xp was flagged to boot that flag disappeared.

 

I know I could make ntldr do the job but it's just not

worth the time

and effort now.I.m happy with the way it is right now.

I think that Windows reads the disk geometry from the bios,but

Linux does not, it reads the disk geometry directly from disk,

so it doesn't need LBA. I don't know why they made laptops so

they couldn't switch to LBA in bios.

I tested this (am replying from Ubuntu) and the boot.ini method works

although I have a desktop and LBA enabled. My experience was that I

got practice deleting and reinstalling my Linux distributions. :-)

Let me ask you a question. Have you put this software on your dual boot

setup?

http://www.fs-driver.org/index.html. It reads and writes to ext2/3 for

Windows.

My Ubuntu install is now L: drive in Windows and Swap is S: drive.I named

them.

No, I didn't know anything about it. I see one warning,

"If you mount an Ext3 file system as an Ext2 file system and the file

system is not cleanly dismounted, (e.g. due to a system crash), you have

to run the e2fsck tool. (Linux does it automatically.) Running e2fsck

can take several hours on large volumes. You do not benefit from

journaling the Ext3 file system, because you have to run e2fsck."

 

I ran the automatic install for installing Ubuntu on the largest free

space. I think it made everything Ext3 except the swap file which is 82.

 

I deleted most of the Acronis Secure Zone which is fat32. So I had

a partition which Linux and Windows could share.

mkdir /mnt/share

mount -t msdos(or vfat) /dev/sda5(my fat32 F: drive) /mnt/share

Then you also have to umount it so one can make manual scripts for

both operations which is like a batch file or put it in fstab which

is automatic. So you can transfer files, but it takes reboots.

This Ext2IFS_1_11.exe may very well work better.

You can email me at "TeX" plus "tonyx", one word, at gmail dot com.

since the topic is drifting away from Windows XP, if you like.

The only reason I asked about the exts read/write software is because the

other day Windows

left some kind of 1kb file on the drive without me knowing about it. I don't

know if that would be a problem or not. Ubuntu doesn't show the file. I might

reinstall the program and set the Linux

drives as read only to avoid that situation from happening again. I don't

see any way of doing it

from within Windows.

http://www.fs-driver.org/faq.html#not_sup_feat

 

"The current version of the Ext2 file system driver does not

maintain access rights. All users can access all the Ext2

volumes that a drive letter is created for. For example, if

a drive letter has been created for an Ext2 volume, which is

the root volume of a Linux installation, you can simply read

and modify files such as /etc/passwd and /etc/shadow. User

names are readable and passwords of these users can be quite

easily cracked and modified!"

 

SH: Perhaps your situation is also dangerous, I don't know,

are you the sole user? The program below is designed to do

what you are thinking of doing now, making Linux read only.

 

http://www.diskinternals.com/linux-reader/

 

"How to get safe and quick access to alternative file systems?

DiskInternals Linux Reader is a new easy way to do this. This

program plays the role of a bridge between your Windows and

Ext2/Ext3 Linux file systems. This easy-to-use tool runs under

Windows and allows you to browse Ext2/Ext3 Linux file systems

and extract files from there.

 

There are a number of evident merits of the program, which

you should know. First of all, DiskInternals Linux Reader is

absolutely free. Secondly, the program provides for read-only

access and *does not allow you to make records* in Ext2/Ext3

file system partitions. This guarantees that the interference

in an alternative file system

will not affect the work of Linux later.

 

Apart from this, it is necessary to note, that it gives you an

opportunity to use common Windows Explorer for extracting data.

A preview option for pictures is one more pleasant point, which

is worth mentioning."

 

SH: I will download this, experiment and let you know the results.

Well, it seems to work well, I extracted a Ubuntu ebook

from my Linux home partition and imported it into Windows.

It didn't ask me for any money yet. I think the Fat32

partition will still be necessary as a transport point

to import files into Ubuntu so they can be "journaled".
