I had Ubuntu 11 installed, and now I want to install Windows 7. I formatted one partition (with the help of Ubuntu's live CD) and I started installation of Windows. I formatted the partition again and Windows' setup started copying files. After that the computer rebooted, and on screen some text appears about voltages and the message
Verifying DMI Pool Data ......... Update Success. The installation stops here.
I searched on Google for some solutions, but the one thing that I found is that Windows can't detect the hard disk.
I tried installing Ubuntu again and there was no problem, I'm very confused.
The first time I installed Ubuntu, it was the 64-bit version, but my system is 32-bit. Ubuntu started updating and the system crashed, I tried to install windows, but I can't (as above) so I reinstalled Ubuntu.
I also tried to delete the Ubuntu partition and installing Windows there instead, but that didn't work either.
