Hi

It would help to know more about the linux systems that you have installed and on pen drive.

Also no need to duplicate post

What you did was delete the larger part of the boot files for your Linux distribution. Which Linux distribution were you using? Do you want to install another distribution of Linux or reinstall what you previously had? Do you get the error message when you select to boot your Linux from the Grub menu? are you able to boot windows? If you have a windows installation CD/DVD you can select repair when you boot it to fix the mbr to boot windows. If you want to install/reinstall Linux, you can use unetbootin to put a Live CD on a flash drive. Go to the link below and download it. You can do it from windows so select the correct version to download. You didn't actually say whether you can boot anything so...?

I must suppose the error message is from GRUB's primary bootloader which is still installed. As indicated you can use a Windows' repair disk to restore the Windows bootloader. This means you have no need to reinstall Windows.

The suggestion about trying to boot from a USB live CD image can be your salvation. If I were in your situation I would definitely try it.

Assuming you have a bootable Linux on the pen drive,
1) with the laptop turned off, plug in the pen drive.
2) turn on the laptop and edit the BIOS boot menu to poll the removable drive for a bootable OS before polling the hard drive.
3) save and quit the BIOS.
4) it should boot the Linux on the pen drive.
5) once Linux is up and running, you can then recreate the Linux partition and reinstall Linux in that's what you want to do.

Otherwise, you will need to repair the MBR to boot into windows. Without a cd drive and windows recovery disk, I don't know how you would go about doing that.

Check the link below. It is a windows 7 forum for your windows problem and it does have one solution if you have your windows 7 disk. If you don't you may need to google to find some disk you can download to use.
