hi and thanks in advance for any help, guys 1. I installed DDS 10 & the OS Selector on my XP MCE 2005 comprising single disk with 2 primary partitions. 2. DDS shows me 7.3 MB unallocated space which DOES NOT show up in Windows Comp Mgmt... thats my first confusion. 3. When i use DDS (manual mode) to increase the unallocated space to 10 GB, it asks for REBOOT after commit. But when i restart, it hangs at the boot screen. 4. OS selector works fine either way, whether i reboot due to DDS or during other, normal use. cheers..
