So in Windows Seagate 200GB is seen as a SCSI disk.NOTE: I have preserved the NTLDR bootloader on the Seagate 200GB and I need to switch the harddrives priority in the BIOS so the Western Digital Raptor 36GB is the first drive to boot to load Grub.The problem is that when I try to boot Windows XP in Grub I get an error that the selected disk does not exist.On Linux the disks are detected as:sda = linux (sata) (hd0,0)hdf = windows xp (ide) A partially logical mapping for the ide-disk, hdf, might be (hd5,0) but I only think Grub goes up to hdd.I get this error with Grub, so it might be some reconfiguring of BIOS, connector-setup, or something else.Booting Windows XP rootnoverify (hd5,0) makeactive chainloader +1 Error: 21: Selected disk does not exist Press any key to continue ...The question is.. How?The easiest solution would be to throw my ASUS P5W to hell! This was a good buy, half of new price with warranty, but still I've heard of people doing just fine with Jmicron and many good reputated mainboard come with that controller, although it's not that kind to Linux.

With help from my dear friend julemand101 ..In commandline issuing "boot (" and pressing tab sh
might run into this problem as I have just done when installing CentOS 6. When you first re-boot to go back into Windows and select "Other" from the Grub loader menu you are presented with "Error 21: Selected disk does not exist". Almost as uninformative as it is annoying, but it can be fixed at least in my case by the following: - Log into Linux, and run the following as root: - vi /boot/grub/menu.lst You'll see something like: - # grub.conf generated by anaconda # # Note that you do not have to rerun https://bbs.archlinux.org/viewtopic.php?id=31595 grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,0) # kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00 # initrd /initrd-version.img #boot=/dev/hda default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-53.1.4.el5) root (hd0,1) kernel /vmlinuz-2.6.18-53.1.4.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet initrd /initrd-2.6.18-53.1.4.el5.img title other rootnoverify (hd1,4) chainloader+1 What I had to do was https://iansramblings.wordpress.com/2011/11/21/grub-error-21-selected-disk-does-not-exist/ change the last (hd1,4) to (hd0,0) then I changed the title to Windows instead of other. I also set the default to 1 so it defaults to windows and increased the timeout to 20.

Plan to use GRUB for multiple booting to select the OS but only with luck have I got it partially to work. Windows 98 and Puppy 431 O.K on first HDD but Puppy 421 on second HDD /dev/sdb1 stops at error 21. My setup is as follows Partition Filesystem Mount Point Flags OS (Operating System) /dev/sda1 fat32 boot,lba Windows 98 /dev/sda2 ext2 / - Puppy Linux 431 linux-swap - - Puppy Linux 431 swap space /dev/sdb1 ext2 boot Puppy Linux 421 linux-swap - - - Puppy Linux 421 swap space Additionally can anyone tell how might add an option to EXIT via Grub. I have pasted my Grub file menu.lst file to look at or editing if you so need to. This will be a bulky and untidy script as I tried everything I could think of to get it partially working such placing it in MBR of drive and root of partition. The pasted text from the Grub menu.lst is as below # GRUB configuration file '/boot/grub/menu.lst'. # generated by 'grubconfig'. Fri Mar 4 18:06:16 2011 # # The backup copy of the MBR for drive '/dev/sda' is # here '/boot/grub/mbr.sda.29378'. You can restore it like this. # dd if=/boot/grub/mbr.sda.29378 of=/dev/sda bs=512 count=1 # # Start GRUB global section #timeout 30 color light-gray/blue black/light-gray # End GRUB global section # Other bootable partition config begins title Windows (on /dev/sda1) rootnoverify (hd0,0) makeactive chainloader +1 # Other bootable partition config ends # Linux bootable partition config begins title Linux (on /dev/sda2) root (hd0,1) kernel /boot/vmlinuz root=/dev/sda2 ro vga=normal # Linux bootable partition config ends # Linux bootable partition config begins title Linux (on /dev/sdb1) root (hd1,0) kernel /boot/vmlinuz root=/dev/sdb1 ro vga=normal # Linux bootable partition config ends title Install GRUB
