Here's the situation. I installed Ubuntu using the along side option. Everything went ok. When I restarted I went strait to Ubuntu and it worked beautifully. When I restarted and tried to enter windows, the loading screen appeared, and after 3 -4 seconds it restarted again. No error, no cursor waiting, no nothing.

I looked on the internet for help and found several resources.

I tried first lilo since it seemes that many people had they're issues solved with it.

After lilo neither ubuntu nor Windows would start.

I installed and used bootinfoscript. The RESULTS.txt can be seen below

After that I looked at

Boot-Repair

I did as instructed here

Can't boot XP after Ubuntu Installation, how to fix?

,meaning I redid the mbr of my Ubuntu install using a generic mbr.

with no success. The results of boot-repair are in the first link.

Now when I restart my computer I don't even get the windows loading screen, just

Missing operating system
Missing operation system
Operating system not found

that's it.

I did not use the fixboot or fixmbr option because I don't have a windows cd cabable of seeing my hdd drivers. The usual XP windows setup tells me that I have no hdd.

Please help, I don't know what to to next. This is my first time with Ubuntu or any Linux OS.

You'll need to boot off the Ubuntu LiveCD and re-install grub and configure it. Instructinos are here:

One possible reason for Windows not booting is that the base operating system was damaged during the partition re-size operation. A possible cause for this is an inconsistency in the data.

This is why we normally recommend a few steps before installing alongside Windows:

  1. Backup your data and make sure you have a Windows boot disk or some other recovery option
  2. Run chkdsk on the drive to make sure there are no errors.
  3. Defrag the drive so that the re-size operation has as little work to do as possible and that it goes quickly
