I’m using Windows 7 and every time I restart my computer, it goes to a black screen with a single blinking white line in the top left corner, stays there for about 30 seconds, and then continues with booting. I installed an SSD and one of the things it’s supposed to do is boot quickly but this screen is keeping it from doing that. I searched around and thought it had something to do with the system partition that was on my HDD that I was using as my OS drive before but I deleted it (though I haven’t been able to get rid of the partition entirely, it’s unallocated space) and it’s still doing it. Anyone know how to fix this? Would actually merging the system partition that I deleted into the main drive fix it?
This is a common issue often related to the OS being the OEM version, it can be solved by fixing the master boot record and reconfiguring the bootloader. Try this:
- Put the Windows 7 installation disc in the disc drive, and then start your computer.
- Boot from the disc
- Select a language, a time, a currency, a keyboard or an input method, and then click Next.
- Click Repair your computer.
- Click the operating system that you want to repair, and then click Next.
- In the System Recovery Options dialog box, click Command Prompt.
Type:
Code: Bootrec.exe /FixMbr
Code: Bootrec.exe /FixBoot
Code: Bootrec.exe /RebuildBcd
Press ENTER after each command.
Restart your computer.
Okay so I got around to trying this. I don’t know if I did something wrong but doing what you said added the Windows installation from my other HDD to the boot manager and didn’t fix the white line thing. There was a repair pop up when I got to the repair screen though, and doing that fixed it. I just had to remove the second OS from the boot screen. This seemed to have fixed it though.
