I saw Ubuntu 12.04 yesterday and decided to install it.
First I went to the BIOS, then selected Security> I / O interface Security> New interface card and set it to locked. This is the only way I can get into Ubuntu.
Next I installed Ubuntu the usual way. It worked great(except for the login sound; I missed it).
Then I went booting into Windows 7. The Windows logo kept spinning as usual, then it stopped. Next my computer restarted itself and said that there is a "problem" with Windows so I have to run the Windows recovery partition to repair. Then it goes through a 1-hour long process and restarted again. I chose Windows from the GRUB menu and Windows booted.
The question is: What is the anonymous problem that happened to Windows? I am planning to re-install Ubuntu now (because I messed with the boot screen, now it's gone and shutting down takes forever) and I don't want to run into that problem again.
Any help will be appreciated.
Edit: Re installed Ubuntu and this time nothing happens.
