Public bug reported: Binary package hint: grub2
I first asked for help here: http://ubuntuforums.org/showthread.php?p=8085933 but it seems that it is a bug candidate so I am filing it now. First of all here is my setup: === BIOS HDD Boot Order === #1: SATA 160GB #2: PATA 80GB === HDD DETECTION Order === Primary Master: DVD Secondary Slave: PATA 80GB Tertiary Master: SATA 160GB === Where are the OSs installed? === SATA 160GB First: Windows XP Pro (drive C) Second: data partition Third: Karmic === How I installed Karmic === 1) I first disconnected the PATA 80GB drive. 2) I installed Karmic, formatting the previous ext4 partition where Jaunty resides. 3) Boot Up [It detected WinXP fine and it loads] 4) Shut down 5) Re-connected the PATA 80GB drive. === The Problem === Once the PATA 80GB drive is connected - Karmic detects it as /dev/sda. My SATA 160GB is moved by Karmic to /dev/sdb. At this point, it is okay. But when the system runs update-grub (after an upgrade for example) it re-creates the grub.cfg. However, it based it's new settings on what Karmic provided it which is: PATA 80GB as /dev/sda; and SATA 160GB as /dev/sdb Once I reboot, Grub2 will give this error when choosing WinXP OS "error: invalid signature". And grub2's menu is reporting that WinXP is on /dev/sdb. BUT, prior to this new grub.cfg update, WinXP was loading fine and reported on /dev/sda. Pre-Karmic (ie Jaunty, Hardy, etc.) it follows the HDD boot order I setup on my BIOS. But with Karmic, it follows the "HDD DETECTION Order" (see above for reference). Currently, to fix it, I have to disconnect my PATA 80GB drive, reboot the PC, edit the "Karmic" GRUB2 menu line to point it to /dev/sda (since it is now pointing to /dev/sdb), run update-grub again. Then reconnect the PATA 80GB drive and everything will work again as it should be. I do not know why Win-XP will load on /dev/sda even though Karmic and Grub reports/moved my SATA 160GB to /dev/sdb. Attaching additional files that may help.
