Marking boot manager ( bootmgr) in Windows 7 as not compressed from within Linux


Here's my problem:
While choosing to compress certain folders from within Windows 7, I marked the boot manager as 'compressed'. Now, when I try to boot, I'm not able to boot into Windows 7, or any other OS (I get an error: bootmgr is compressed, press Ctrl+Alt+Del to continue, which restarts the system and the same cycle continues.


I have a Windows 7 + open SUSE + Ubuntu 10.04 LTS wubi install boot setup. To complicate things, its a laptop, and the DVD drive is conked. Is there any way I can boot into any of my OS's? If not using a live boot, can I, perhaps make a bootable USB flash drive, boot into it and uncompress the boot manager ?


Note: I'm typing this from another desktop, and I do not have Windows installed on this.

Used this: https://serverfault.com/questions/137877/decompressing-files-on-an-ntfs-volume-from-linux/137906#137906 Still no go, getting the same error message.


Answer



Well I had to take a different approach since I didn't have access to another Windows-based PC.


Tried couple of extra tricks with unetbootin, but none of them resulted in any success. Finally, I used SuperGrubDisk via unetbootin and got access to my Linux partitions. Once I got access to my openSUSE partition, I used VirtualBox to install Windows 7 in a VM. Once Win 7 was installed, booted into it, and created a bootable Windows USB disk. Finally, booted using the USB drive, went to Recovery mode, selected to uncompress the C drive, reinstall the bootloader, and everything's fine now.
