Sounds like you have a hard drive issue

by NickNielsen In reply to UNMOUNTABLE_BOOT_VOLUME

and the master boot record is corrupted. You have two options:

- Boot to your Windows CD and select the REPAIR option when it's presented. I would try this first.
- The remaining option is to run the Acer recovery software. http://www.pctechbytes.com/acer/acer-aspire-system-recovery-partition
Warning: Running the recovery program will restore your hard drive to the factory condition. Before running the recovery, make sure you back up all your data from the hard drive. If you don't do this, all your data and programs will be lost. You may need to seek professional assistance.
