XP will boot from another partition too. hda1 or sda1 is not a option for it. But it will install its own bootmanager into the mbr. So save yourmbr first with dd (BEFORE you install XP!!!!). You can put the etchbootimage onto your hard disk and call it by the XP bootloader by setting aline to the XP boot.ini (save it on a usb-stick e.g. to transfer it after the XP is installed).But I want to install XP in another disk, different from which etch is installed. So XP will install its own bootmanager into the mbr of this different disk. Am I wright? Remember that I can tell the bios from what disk the system boots. I gues I can use this in order to make the system boot from the second disk, where XP is being installed, making XP ignore the disk where etch is installed.
XP will install it into the Master Boot Record. That's the one on the first disc who is to boot. Changing the boot priority or the order of the disk could cause troubles.
You wrote, that you are Using the first IDE disc as hdcNormally the first disc is hda, so have you a DVD Rom or something like it connected as primary master? If XP will write its bootloader onto the mbr of the 2nd disc if it is remapped by the bios I don't now. It is a risk to lose your bootmanager on the first disc if windows won't get the trick. Therefore I would save the old mbr for any evil case.
If you have a SATA disc: dd if=/dev/sda of=/home/[your username]/etch.lin bs=512 count=1Both disk are ATA, not SATA. The line is the same in this case?
primary master is hda primary slave hdb secondary master hdc secondary slave hdd If it is a primary master, the line is dd if=/dev/hda of=/home/[your username]/etch.lin bs=512 count=1
Insert this line into your xp boot.ini (if XP uses the partition as C:\ ):c:\etch.lin="Debian Etch" That gives you a new bootoption in your XP bootloader. From there you can start Etch again and repair the grub bootloader if you want to stick to grub.Thank you!
No problem :) cuPierre
