Hi, I installed XP (work related reasons only) on my 40 GB laptop. No problem. I then booted with SuSe 10.1 (64 bit) SuSe recommended re-sizing Windows and certain partitions. I accepted all recommendations. SuSE did well, all hardware came up properly. SuSe installed GRUB. Re-boot gives option of XP or SuSE. SuSe starts up as expected. But when I select XP the Windows splash screen appears and things hold up for about 10 seconds and then the BIOS starts its re-boot cycle and I get GRUB again. Because the Windows splash screen appears it is as though GRUB is re-directing correctly to Windows, and because it fails I suspect that SuSe has, somehow, upset Windows (maybe during the re-partitioning). Any ideas? Maybe, before I install SuSe, I need to either (a) switch off XP's 'recovery' function (I tried that, but it fell over) or (b) prevent the use of a swap file (I can't find such an option) Any ideas ? Thanks for any suggestions. Colin
