Remount windows 7 boot partition in arch linux


Hey there,

I was installing arch linux onto my pc, besides windows 7,
as I accidentely unmounted the boot partition of windows. Does anyone have an idea how to remount and where to mount it? Allready tried "mount /dev/sda1 /mnt" but by booting windows it only keeps saying "Missing operating system".

Any help would be really great. Thanks in advance, Julien

Sounds like you removed it, not "unmounted" it.
Go to bootinfoscript and download the script - run it and post the RESULTS.txt as it says.
Looks like it is also in AUR if you have that enabled.

Sorry for taking so long. Hope it's anyhow possible to get windows back to work

You erased the M$oft "System Reserved" partition - what in Linux we'd called /boot.

Nothing else for it but to boot your Win7 CD and go through recovery - I found an article on technet when I needed to, so a quick search should find it for you. If you don't have a Win7 CD, it used to be you could download a recovery image and use that just for this sort of situation - not sure if that is still true.
Your data, and the Win7 system is still there, you are just missing the boot code.

Before you start, reformat /dev/sda1 as NTFS (after saving anything there), and remove the boot flag from /dev/sda3 - Windows boot-loaders won't boot with two boot flags, and I'd bet the recovery environment will be likewise.
