Here's my situation, I'm setting a friends computer back to Windows (I know...) but they're not computer savvy, and it's just easier for them. The problem is that GRUB won't allow the computer to boot from CD. I have the windows disk in, but GRUB always boots Ubuntu instead. I've changed the settings in bios, and it tries to boot from the cd, but just doesn't. I don't have a floppy boot disk handy, so this is what I need.

1. A way to remove GRUB and/or format the MBR from ubuntu

or

2. A way to make a DOS boot floppy disk from linux (most of the boot disks come in .exe self extracting format that don't work in ubuntu of course).

Please help,

Thanks

First, GRUB will not stop the computer from booting from CD. That is a BIOS function. If it won't boot from CD, fix that before doing anything else. Have you tried several different bootable CDs? (The windows install disk could be the problem.

To install a **Windows** mbr from Linux, you would need an image file of the actual Windows code.

Yeah I've tried 3 bootable cds, two different windows cds, and ubuntu live... none of them will boot. It appears to be able to boot from the floppy drive, but I don't have a bootable floppy disk.

I know the drive works, it reads all the cds I put in it when ubuntu is booted, plays audio/video and such.

I guess the bios is too old and doesn't allow booting from cd. That's no problem. Get smart boot manager, put it on a floppy and boot the windows cdrom from the floppy. I've read in linux format that smart boot manager can do that. I've never tried it, though.
