I have a MacBook Pro Mac OS X v10.4.10, 2.16GHz Intel Core 2 Duo, 1GB 667 MHz RAM.

Need help with Parallels. I installed Parallels Build 3188 in June 07. It has been working fine until today. When I tried to run Parallels this morning, as I have done many times before, I got an error message "UNMOUNTABLE BOOT VOLUME" and no amount of resets or restarts, even under safe mode, work. Pretty frustrating.

Will an upgrade fix this? Or should I uninstall and reinstall Parallels? Will this affect my existing windows files?

Most most grateful for any bit of assistance. Thank you.

Welcome to the MacNN Forums! It sounds like Parallels has gotten goofy about your Boot Camp partition. This could be because the partition itself is messed up, or Parallels has lost some data about it.

The first thing I'd do is (assuming I'm right about your use of a Boot Camp partition) is try to boot into Windows. If that works then you're fine-just delete the Parallels virtual machine that depends on Boot Camp and have it build a new one.

If it doesn't boot...your problem is the Boot Camp partition. Maybe the partition is fixable, but more than likely not. If you can access it from OS X (which can read NTFS and FAT32 partitions just fine), then copy your documents and other important data and get ready to delete and rebuild that partition.

Let us know what you find, and we'll all be happy to help you make things better.

boot windows to a recovery console.. then run chkdsk /r

let it run and that sometimes cures the unmountable boot volume
