Upgrading from Vista to Windows 7

[Chirag Borawake]

Hello all,
My cousin owns Toshiba Satellite L305-S5937 Laptop.
It has only two disk drives, C and D.
Currently C has windows Vista.
So I tried installing Windows 7 on D drive.
The windows setup installed everything, restarted, it showed 'Preparing windows for the first time' and 'Checking video performance'.
Welcome screen appeared.
After that, it restarted again on the welcome screen, saying- logging off, windows is shutting down.
This time when it started, beyond toshiba screen, it said:

'BOOTMGR is compressed'

What does this mean?
I never had such a problem with installing windows.
Even vista wont work.
So i booted from the disc again, thought of jumping onto vista again.
Formatted the drive from windows installation disc, on which i installed windows 7.
Restarted again.
Still the problem is the same.
BOOTMGR is compressed.

What should I do??
Any suggestions would be appreciated, and the best answer would be the one, which works for me.
Thank you in advance...

The D: drive is likely the restore partition. I would guess it has something to do with that.

If you dont have precious data on drive c:, then reinstall windows 7 on drive c: with a format. If you have data on drive c:, then try to install windows 7 by upgrading the Vista

Ok, that makes sense. But I thought that I wouldn't get any drivers for windows 7 for that laptop.
So planned to install it side by side, check if the drivers are working that i downloaded. If they work, i would have formatted windows vista...
Can you tell me where I can get drivers that will surely work for windows 7, confirmed???

If there were drivers for Vista, there is a 99% chance everything will work just fine in Windows 7. Remember, W7 uses Vista as a base, and they are so similar under the skin that Vista drivers sometimes work on W7 with no changes.

The majority of drivers made for Vista will work in compatibility mode under Windows 7, so no worries.
