The bug is affecting IBM R52 laptop as well. I have installed i386 Ubuntu 7.04 and grub on external USB drive using alternate CD. I must mention that I chose not to follow installer suggestion to install grub to my internal HDD and installed it on my USB HDD instead. I can boot into grub, but get error 15 unless I manually edit menu.lst and change (hd1,0) to (hd0,0). The boot order in BIOS is not affecting which drive is hd1 and which is hd0.
