I've been struggling with a pitifully small virtual C: partition on a Vista VM, and so I tried to expand the hard disk. Happily (as will become clear), I took a backup copy of the .pvm package first, then selected <Virtual Machine>, <Configure...>, <Hardware> tab, <Hard Disk 1>, <Edit...> then dragged the slider to 64.2 GB from its original 31.2GB ("Resize file system" and "Expanding disk" were both ticked/checked). An appropriate amount of progress bar movement took place, and all seemed to be well. Then I noticed that the Hardware tab still said "Expanding disk, 31.2GB", but I assumed it might refresh itself the next time I started the configure tool. Then I attempted to boot the VM, only to be hit with a BSOD "UNMOUNTABLE_BOOT_VOLUME" error. I restarted the VM, with the same result. I've just restored the backup .pvm, and it's working again. However, I still have a too-small C: drive. So, has anyone actually managed to resize his or her virtual hard drive? If so, what's the secret? (I should have said that I'm using the latest build [14922] of Desktop 7.) For those who've read this far, many thanks.
Thanks It's odd that, apparently, we're the only two people to have experienced this problem. Good luck!
I've searched and seen others.. I have also tried all the ideas outline here and with Microsoft to fix the VM. I expect to speak to someone today at Parallels about it. I didn't do anything odd, just increased the disk size from the PD7 GUI.. one thing that might matter is that I did "Run Out of Space" in the VM before I increased the size.. perhaps that corrupts it.. There has to be more.. I am running the latest vesion of PD7 (Just Upgraded) and MacOS X 10.7.2 - 2.2GHz Core i7 with 8GB RAM.
I've done this many times on Parallels 6 and earlier. Been using Parallels since version 3. Haven't tried it on Parallels 7, but I am having another problem on Parallels 7. Note that I have experienced bugs with Parallels upgrades in the past. Sorry this doesn't answer your question directly.
i suggest you to run check disk - it might help (it helped me several times when i was in a session with users with this kind of problem). So, start you virtual machine (backup - you are right. Don't forget this time as well). Go to start > run > cmd. put the following: chkdsk /r than type Y and restart the VM. Wait until checking is done and try again
