CD boot ?

[dagles]

Hi there,

How can I run debian residing on my primary master pata disk when booting from CD ?

For some reasons (don't need to be explained) I can't boot anymore from hard drive where I installed my debian. It is not a problem of HD but a bios problem.
The only thing I can boot is CD.
Is there a way to run (boot) the debian on HD ?

I've tried to make bootable grub CD and copy my menu.lst to this cd the boot, but grub reports error 6 : Mismatched or corrupt version of stage1/stage2


Anyone can help ?

seems to me like you have a grub problem not a bios problem. try to boot from the cd and rewrite grub to the MBR

well the problem is not the invalid mbr, because I can boot from PATA HDD normally when no SATA disk is connected.
The problem for what I use CDROM booting is that bios can't initialise boot from PATA drive when there are some SATA drives connected. And no setup in bios boot sequence will solve this. (proven)

So I need to boot from CD. Formerly I used free dos bootable CD. First booted the dos and then from freedos boot menu I choose boot from first disk (0x80) and this works well. But I've changed my SATA controllers because old ones are broken and after that point this method even not work. The grub freezes at "Please wait loading grub" point.

So I tried to create grub bootable cd from originaly booted debian (without sata drives). But after booting from this CD and starting the boot from HDD from grub menu ( root (hd0,0) kernel=/boot/vmlinuz..... etc. ) I've got grub error 6: version mismatch between stage1/stage2

and this whole sucks.

Any suggestions ?

Some motherboards are tricky. For example mine won't boot if somehting is plugged in the secondary IDE channel while SATA is in use (when "enhanced-mode" is selected in BIOS SATA settings). A BIOS upgrade might help you with this. Or carefully read your motherboard manual, there may be a workaround, if no real solution exist.

Maybe you could wipe GRUB from your hard drive ("firmbr" or something), then booting from a CD could work.

I use SmartBootManager to boot into reluctant PCs it provides both floppy and CD images and normally picks up any bootable partition
