Short version: first confirm how Ubuntu was installed — Wubi (inside Windows) or a normal partition — because the removal steps differ. was right to ask that. If it was a Wubi install the uninstaller in Programs and Features or the uninstaller in C:\ubuntu is the correct route; if it was a real partition you must remove the Linux partitions and restore the Windows boot area. (wiki.ubuntu.com)

Practical checklist (do these in order and make a full backup first):

  • Back up important files (external drive or image).
  • Confirm install type: look for C:\ubuntu, C:\wubildr*, and an Ubuntu entry in Programs and Features (Wubi) — uninstall if present. (wiki.ubuntu.com)
  • Remove any leftover Linux partitions (Disk Management or GParted) making sure not to delete Windows partitions; leave space unallocated or extend C: only after you’re confident.
  • Restore the Windows bootloader using the Windows installation/repair media (Startup Repair or the recovery command-line tools described by Microsoft). This is what and were pointing at. (support.microsoft.com)
  • Repair filesystem and system files from Windows: run a full disk check and then run the System File Checker to fix corrupted system files (for example run chkdsk appropriately and then sfc /scannow). These fixes often stop the repeated recovery/reinstall loop. (learn.microsoft.com)
  • If Windows still fails after the software fixes, test hardware: run a thorough RAM test (MemTest86) and check drive SMART / run manufacturer diagnostics or smartctl to rule out failing RAM or disk — recurring corruption that needs reinstalling usually points to hardware. (memtest86.com)

If those steps don’t stop the problem, avoid repeatedly reinstalling: image the disk, swap the drive or RAM for testing, or have a repair shop run hardware diagnostics. ’s live‑CD approach is useful if you need to run tools outside Windows, but prioritize backups first.

How did you install it?
Did you use Wubi(installed alongside windows)
or did you partition the hard drive
I think its a lot easier to remove if Ubuntu just runs with your current system

Do you intend to install another Linux distro, or do you just want to recover the drive space?

Basically, you need to restore the master boot record. Here are a couple of links that help:

1.)Boot the windows repair/installer cd and chose the command line. Enter FixMbr and if it doesn't work then enter Bootrec.exe/FixMbr
2.)boot to windows and use the default partition manager to delete the partitions where the linux is installed.

There's a way to recover the MBR by using lilo but you'll need to execute it before uninstalling linux ubuntu. If you have uninstall, then you'll need to boot linux by live cd mode or through flash drive. Then install lilo from teerminal and execute the string.
