Windows 7: Operating System Not Found ?

Operating System Not Found ?

Hi,

I've a laptop using Mandriva Linux 2010.1, and i'd like to install Windows Seven, not on dual boot, i want just Seven. Problem is i receive a "Operating System Not Found" message when i try to boot from the install-DVD, and Mandriva launches from HDD.

I thought it was a broken DVD but he runs well on my other PC.

By the way, i was using Mandriva 2010.0, i've installed 2010.1 yesterday with a DVD. That DVD does not run anymore either. But i can read audio CD or DVD movies so it's not an hardware issue.


Can you help me please ? Thanks in advance. =)

PS : i can't use USB-stick.

Hello Eshelia,

You will have to format the drive to NTFS first. Because Linux is on it now, windows will not see a partition.

Now that i re-read your post i dont know if thats your problem. Sounds more like a disk problem.

Thanks for your answer. =)


No, i guess it's not a partition problem. When i first tried to install Seven, he asked me to reformat in NTFS. But my first DVD was corrupt, so i had to use my guarantee and change my DVD. But because my HDD was formated in NTFS, i had to reformat in EXT4 with Gparted and reinstall Mandriva Linux too. But since that, i've this "Operating System not found", with the Mandriva DVD or the Seven DVD.

Mandriva Linux boots fine with my HDD, so i think it's not a disk problem. Maybe a DVD lector problem ? But he reads Audio CDs and DVD movies just fine so...


(btw, sorry for my english, i'm french)

Hello Eshelia, welcome to Seven Forums!





If there's nothing at all you want to save on the Hard Disk Drive (HDD) have a look at the tutorial at the link below, this method over-writes everything, all the old code on the entire HDD and gives you the best possible space to install Windows 7 to.

Thank you Bare Foot Kid, but i think i can't do this since the DVD does not even boot.

If you can create this on another Windows 7 PC, see if it will boot the Lappy.
