Big f*ck up

Hello people,

I made a huge mistake while trying to make a bootable flash drive for proteus.

On my win7 machine I ran that .exe that makes the flash drive bootable from my desktop (regretted almost instantly as I knew what was going to happen). Now I can't boot into windows and there's an error that says Syslinux: No default or configuration directive found. I may have posted this on a wrong forum but please help it's my brothers lap top which makes things even worse!

Is there something I can do from Proteus since I'm currently using it from my usb stick.

Welcome to Porteus. We have to wait for Ed_P, windoze specialist. :)

And what "that .exe" are you referring to? Name please.
(regretted almost instantly as I knew what was going to happen).
Sounds like you knew you specified the hard drive rather than the USB drive. C: vs D:?
Now I can't boot into windows and there's an error that says Syslinux: No default or configuration directive found.
When you try to boot into Windows is the USB drive plugged in? How are you trying to boot into Windows, is there a menu to choose what system to boot?

You are so screwed. If he is an older brother consider living with a neighbor for a few days.

Well at least something worked.

Can you open a terminal window and do a command and post it's results?

Code: Select all

ls /mnt/sda*

You have overwritten the mother boot record. Two options.

1) Run your windows disk and repair the mbr. Run a windows repair disk and run fixmbr

2) Boot windows from the syslinux bootloader.
