Why did this happen? Was it some setting I did during install? Forgot which ones it asked me for.. Annoying how it asks you to select some options without explaining what they are.
Seriously no one in the forum can answer this question.
However, whatever you did, or the installer did, or the bug did to your hardware, the are still left inside the hard disk.
If you really want to spend lots lots of time to probe, you can eventually figure out and not to repeat, or even if repeated it can be recovered to working condition.
So no fixer worked in mint... I uninstalled grub and now i can't boot into anything I just get an error message like no system file or something when I turn the comp on.
How do I get windows + mint working again?
Computer boot up with bios and bios pass to boot loader to boot whichever OS you choose.
If you delete the boot loader, you should expect computer to stop booting up OS.
Usually one does not delete boot loader or boot manager, one just repair it, or replace by another one that works.
How to get Win7 to work? just use Win7 CD or recovery disk, follow win7 procedure and repair MBR or boot manager.
How to get Mint or Linux work?
boot from Mint CD, run in Live, look at the documentation of grub2 https://help.ubuntu.com/community/Grub2
goto item 12, follow one of the method, it should repair the boot loader.
