Is there still a procedure for fixing an overwritten GRUB bootsector from the live CD?

Or should I use Ultimate Boot CD for this?

(gonna reinstall winxp 32 bit to play games, danged win7 doesnt play anything now , nothing works __{{emoticon}}__

Can you be a little more descriptive on what boots and why things broke?

The live cd has a grub repair section under Mepis System Assistent in AntiX 13.2 if that is what you are running.

I don't think the boot repair on the antiX 13 series iso's actually work. I do believe the last working version was on antiX 12. still available here:

Reinstalling grub from the LiveCD should work.

is the manual for installing grub2:(which assumes you installed on the first hard drive). You may have to also specify a"boot" directory which is also explained.

You need to make sure you have the version of grub right. AntiX-13.2 and later (and perhaps some earlier versions) use grub2. To fix it you want to use the grub2 installer. If you used legacy grub then you want to use an older version of the LiveCD that has the legacy version of grub. Using the same LiveCD you used for the install should work just fine but the instructions for legacy grub may be different.

antix 13.2 still uses grub-legacy. grub2 isn't on any antiX iso prior to the latest alphas and MX.

Thanks for the correction! I must be on drugs or something. Or just getting old.

Still, grub-install on the LiveCD that was used for installation can be used for repairing the mbr. I always use the"grub" command directly (not grub-install). The

has pretty clear instructions. The"find" command inside of grub makes things easier. OTOH, enough people have had trouble following these instructions that other people tried to fully automate the process.

Start grub with with command:Give it your user password, not the root password if it asks for one.

Use"find" to find which partition the boot loader is on: Then run the"root" command on that partition and the"setup" command on the mbr. If the grub bootloader was on the 4th partition of /dev/sda then the find command will tell you"hd0,3" so you run:The first command points to the partition with the grub files on it. The second command installs grub on the mbr of /dev/sda. Use"quit" to get out of the grub program.

Thanks guys, that should fix it.

What's broke is win 7 on dual boot -->specifically my games dont work so the shit must be reinstalled which will wipe grub.

I have manually reinstalled grub before, it can be done even with a debian cd. But I don't remember these things.

Bitjam,

Is that a way to update to the MBR as well as the grub menu on the hard drive without needing to chroot over to the linux partition on the hard drive first?

With legacy grub this fixes the mbr but it does not alter the grub menu. You have to edit menu.lst yourself. This is also what I would do to install legacy grub on a LiveUSB. The root() command tells grub the partition where the grub files are, including menu.lst. The setup() command writes to the mbr of the drive or partition you specify.

Again, the version of grub (grub-legacy or grub-2) must match or it won't work. But grub should tell you if the files it needs are not on the partition you specified with the root() command.

Lots of interesting stuff here. The solution to my simple problem was to use an old Ultimate Boot CD
I had here, specifically the included Super Grub Disk. Read my partitions and rebuilt grub legacy.
Also works with Grub 2 --SPD 2 also on UBCD.
