Lost access to Windows 7 Drive (Dual-Boot Windows 7 & Ubuntu)

I lost access to my windows 7 drive (Dual-boot windows 7 & Ubuntu). every time I try to run Windows 7 I get the message: Bootmgr is compressed, Press CTRL_ALT-DEL to restart. I could run Bootrec /fixmbr or diskpart or attrib to rebuild my mbr table through DOS command window using my windows 7 recovery CD. The problem I cannot access drive C: where my windows 7 are. I get the error message: Cannot open volume for direct access or system cannot find the drive path or specified. I still can access all my windows folders and files through home folder in Ubuntu. I don't want to reformat and reinstall windows. Is there is a way to run the DOS commands within Ubuntu or any other advice to how to fix this issue.

If the Bootmgr is truly compressed then you'll need to boot in using DVD/Repair CD to decompress the files to get it to boot as shown here: BootMGR Compressed Message at Boot Fix - Vista Forums

Once you know the files are decompressed if it still won't start then Mark Win7 Partition Active and run Startup Repair - Run 3 Separate Times.

GRUB can corrupt Win7 beyond repair in some cases, but to know you've done everything possible there are also these further steps for Troubleshooting Windows 7 Failure to Boot
