I am partitioning my daughters laptop as she will be using it at University shortly. She can then have one bootable version for UNI (virius's and all) and one for Home (clean). The laptop came with XP Pro SP2 preinstalled (No distribution disks) The simplest way to solve the problem I thought was to shrink the preinstalled C: partition creating sufficient unallocated space for the alternative partition. This was successful. I then Copied the Primary partition. This worked and I can now see a new partition (E. Then using OS Selector specifically the OS Detector I set about making it visible. Both Partitions are visible though strangely the copy is now shown as D: rather than E: however I flag it as PRI,Boot,ACT (and all combinations to get it visible). However the next step fails to find the new partion or add it to the boot list of OSS. I can only boot the original C: partition. What am I doing wrong?
