I tried to setup a dual-boot system on our home pc. unfortunately, the cd was corrupted and the installation failed. i then rebooted the system to make sure it was ok. It wasn't. "PBR error" or something like that. so i natually assumed the bootloader was corrupted so i used a windows installer disk to try and fix it. however it asked me for the admin password (which is blank). i entered the correct (blank) password and it said the password was >:( INVALID?!?! anyway , i went with a =reparatory install. i tried the ubuntu installer again and discovered that the window's partition's bootable flag was off. i fixed that and rebooted. But windows STILL wanted to go through with the install. there was no choice and i had to do it. in the end, no data was lost.
feel free to laugh at me if you like.
In my eyes, your operating system is as solid as swiss cheese.
