Recently rebiult PC following unrelated issue - 6 partitions in total on HD, 4 XP and 2 storage; all NTFS. I am suffering a problem I had before the rebuild - I thought/was hoping the rebuild would cure it. I have no 3rd party boot manager, I just use windows - i.e. after the bios I get a DOS'y type window with the 4 OS showing (I have given these specific names like Dad, Ian, Video, and Audio). The problem is that 9 out of 10 times the PC will not boot cleanly into what ever partition is selected - the screen goes to the one giving the safe mode, last good configuration, etc options (the as pressing F8 after the bios boot). Sometimes the Last Good Configuration works but mostly I have to go through the Safe Mode routine and then into the OS following a restart. I have got use to this but it is annoying when you need the PC to boot quickly. I have checked the HD using chkdks and 3rd party utilities - all appears to be OK. Numerous (many many)runs through the XP boot disk using Repair Console and rebuilding partitions and fix boot/mbr have been completed. Any ideas on what I could do get consistant clean boots would be appreciated.
