I have just upgraded a PC for a colleague, who, after much badgering and encouragement, conceded to have a dual boot install of OpenSUSE 10.3 on a second drive. Installed XP Pro on hd0, no problem. Created a FAT32 partition on hd1 using 50% of the disk capacity, leaving remainder unallocated for Linux partitions. Booted to the 10.3 installation DVD and the install to hd1, including on-line updates, went perfectly, until the first reboot, where I get: GRUB Loading stage1.5 Grub loading, please wait... Error 21 At which point everything grinds to a standstill. Restart from the installation DVD and finalize the installation via the "Other Options -> Boot Installed System" option. Then I can log in to a fully operational KDE desktop, where everything appears to be working perfectly. The GRUB files read: /boot/grub/device.map (fd0) /dev/fd0 (hd0) /dev/sda (hd1) /dev/sdb /boot/grub/menu.lst # Modified by YaST2.

I have never experienced any GRUB issues with any previous installs, consequently I have not had reason to educate myself about GRUB configuration. I have unsuccessfully searched for and tried a few Googled suggestions. I need to get this machine back to my colleague soon and I would hate to hand it back as a Windows only box. Can any of you folks here help me out with this? TIA Dave
