) and press Enter.
Wait for the files to load and there should be "Safe Mode" on 4 corners

THE LAST OPTION - "Start Command Prompt".

Boot Manager is compressed
If by accident having compressed the entire boot partition, then Vista will display the following error:
BOOTMGR is compressed. Press Ctrl+Alt+Del to restart
Check points for fixing compressed boot-manager:
* Boot into Windows Recovery Environment (WinRE) and perform a “Startup Repair”.
* If the above doesn’t solve the problem then boot into WinRE again, but when selecting the Vista-installation, then press “Load Drivers” (Instead of “Next”) and use the mini Windows Explorer to right-click the boot-drive and deselect “Compress this Drive” and choose Apply to sub-folders and files.
* If that also fails then boot into WinRE again, and go to the “Command Prompt” and execute these commands:
o compact /U C:ootmgr
o compact /U C: tldr
