1. I have installed Win2k in 1st primary partition (NTFS) of sii3114 raid5 drive array and installed DDS10 - OS Selector is working on this software raid. :-D 2. I disabled the "Force Hidden" option under the Win2k boot in DDS10. 3. I create a 2nd primary partition (NTFS) from DDS10 while in Win2k. 4. I then booted from OS Selector and used it to boot CD WinXP install - setting the Win2k partition hidden (but not forced). WinXP install sees 2nd partition as drive C:, and assigns other drive letters to Win2k - this is OK. Disk C: partition was formatted via the WinXP install but not created by WinXP - this was done in step 3. 5. Installed WinXP. 6. After install had to recover the OS Selector boot - I'll omit details here because its not important - basically I just uninstalled and reinstalled OS Selector. 7. Everything works fine when I set active and hidden partition for Win2k, BUT here is the problem... 8. For booting WinXP, it is set active in the partition info settings, and I can set other partitions hidden or non-hidden, BUT the WinXP partition is marked hidden and it will not let me unhide it - its grayed out. This is dumb - bootable partition should always be unhidden. No matter what I do OS Selector will not let me unhide it. I can unhide and hide the WinXP partition from the Win2k partition info in OS Selector. So, I've even tried booting into Win2k with the 2nd partition (WinXP) unhidden and then tried to modify the partition info for WinXP. But it still show hidden in the boot select partition info and will not let me unhide it. If you try to boot to WinXP you get windows errors with something to the effect it can't find partition. Can we get a fix for this problem? Thanks, Walybare PS - If I create a small (less than 100MB) Fat16 primary partion and install OS Selector in it, this problem goes away. But it wastes a precious primary partition so we need a fix.
