Boot issue after power outage

[Zap Rowsdow3r]

We had a gnarly storm roll through here last night and had rolling power outages. Before I could get to my PC to power it down the power went out for a moment, and quickly came back on. My system powered down, then right back up on its own, then the power went out again. After this The Gigabyte boot splash screen  "Preparing Automatic Repair" then "Diagnosing Your PC". After this a notice comes up saying "Automatic Repair your PC" and gives me the options to shut down or try advanced options. I've tried all of the troubleshooting options given and none work, and when I try to use a recovery disc my system doesn't know the disc is there.  I found that I can boot to windows if I select the "Use a device option and select hard drive. Selecting hard drive boots to Windows and it runs normally, and nothing seems to be different, but every time I restart it goes through the same cycle. I had previously dual booted Windows and Ubuntu but since removed Ubuntu which could be part of the problem. There is also an option listed in the Use a device menu that says "ubuntu".

Maybe it just reset BIOS settings and with it f*cked up the boot order ?

even though you have removed either the physical drive ubuntu was located on or just all the files by reformatting the drive the mbr will still register that there is an ubuntu mbr. the mbr can only be removed through completely wiping the drive with all the mbr's on them, it is usually going to me your main drive or the one windows is installed on by default. As far the wierd boots and issues most likely your registry looks like my work clothes, covered in holes. unless i know the exact extent of the damage i cant help you put it back together. but most of the time when stuff like this happens its best to just wipe all your drives and reinstall the OS. just make sure you have somewhere to off load the important information too first. like plugging in another harddrive then reformatting it and just dragging all your information to it. just make sure to disconnect it before installing windows again, as sometimes it likes to overwrite anything thats in your machine.

So. I've removed the HDD that I had Ubuntu on, and that seems to have eliminated the boot issue. There was nothing on that drive other than a partition with DOOM on it. So I decided to use Steam to delete local files of DOOM on it. Now I'm using MiniTool Partition Wizard Free to completely wipe the drive. The problem seems to be solved as long as I don't use that drive, but I'm hoping that wiping that drive will fix my boot problem.
