The Disk Check
cannot be ignored as it may portend a failing HD.
Move the data off of the HD to external, another computer on network, DVD's or to Skydrive which offers free 7gb storage per Windows Live ID and is cheap to buy more - you can then access your files from anywhere or even sync your machines to your files using Sync Any Folder to Your SkyDrive Account.
Once data is backed up wipe the HD with Diskpart Clean Command
, test the HD with maker's HD Diagnostic
extended CD scan, then repartition in Disk Mgmt or using installer or free Partition Wizard
bootable CD, check file system again, install and copy important data back in only if HD passes all tests.
