It totally destroyed my computer: How do I uninstall linux so that I can get Windows back?

Question

I've tried the class "fdisk" approach to format the partitions as I have a swap partition and a /boot/efi partition, and a root partition, but "only" the fdisk command works. None of the subcommands to delete the partitions work at all!

When I restart the computer, I can open the bios, but everytime it just reloads into scientific linux. I have a windows CD in there, and it means nothing to it, just totally doesn't acknowledge its existence.

Help me!!!

Answer 1

First you need to know what your actually doing! Forget the fdisk junk you can either download Linux mint and install live.



By pressing f12 and booting from a DVD





Or by f12 boot menu with the windows disk the windows disk can format over Linux if you like but to reinstall linux from a USB stick only takes 20 minutes.





This is very easy I wish I could show you but





You tube has a video how to install Linux

Or how to install windows if you have one of those custom motherboards ESC is sometimes the boot menu and sometimes f10





But once you choose the right button for the boot menu you can choose the dvd or USB stick to boot and install from

Answer 2

I had that problem few years ago.



Windows and Linux uses different boot loader, formatting the drive or delete (recreate) partition will not fix the problem.



Here is what you should do:



Bootup from Windows installation DVD or USB

Select Repair your computer

And run these command in command prompt



bootrec /fixboot

bootrec /fixmbr

Answer 3

1 put windows installation disk in

2 reboot (or power on) your computer

3 change boot device to CD/DVD

>different keys for different manufacturers, often one of the following: ESC, DEL, F1, F2, F8 or F10, F11, but sometimes different

4 accept licence etc

5 select custom installation

6 select system partition

7 press format

8 press next and proceed with installation

Answer 4

If Davids suggestion does not work-

What you may have to do is to boot up on your Linux cd....select "TRY" instead of install.

Once running- go to disk utility or gparted- what ever Scientific has....then select your hard drive and delete it.

Then select format- format it to nfts- select the quick method- It should only take a minute. Don't select the one where you overwrite everything- that takes to long.

Once done- back out, shutdown, remove linux cd and try to boot up on your windows cd- it should work then.

1. Enter the bios and look for a setting that tells the computer to try to boot from the optical drive BEFORE booting from the hard drive.

You can then fix the windows bootloader.

If you made any changes previously to the bios to accommodate linux (secure boot, quickboot/fastboot, etc) be sure to change them back to default for windows: or select the option to set all bios setting to default.



If you succeeded in deleting any windows partitions you will have to either hope the "fix windows" option works or reinstall windows.

Good luck

Answer 6

I fixed it! Took forever, but I fixed it!



Had to meddle with the bios and open a hidden command prompt and clean my disk because GPT format was destroying the world.



Yeah, that wiped out all my files, but it's okay. I backed up most of them.

Answer 7

best case you just installed a linux boot loader and overwrote the windows one... booting from the windows cd should fix the issue



worst case you deleted all the partitions and must reinstall windows fully

Answer 8

You need to tell the bios to boot from the DVD drive and then use the advanced option to delete all partitions and then create one to load on.

Answer 9

Insert the windows CD boot off that and see if it can repair the boot partition
