View Full Version : [lubuntu] Cannot boot into windows8 after installing lubuntu next to it

Hi,

installing lubuntu for school work next to my windows8 (which I believe is an OEM installation) on my laptop. Used the regular installation steps for dual boat.

Afterwards couldn't see Windows8 in the GRUB menu so followed some tutorial using grub-update. This way I managed to get windows8 in the GRUB menu but when I tried to boot it it just restarted the GRUB menu.

I tried Boot-Repair. Which gave me this paste:
http://paste.ubuntu.com/23264579/

It also told me to repair bootsector of sda1. So I used TestDisk and copied backup boot to original one. Didn't fix the problem neither.

I can still see the windows system partition fine and doesn't seem anything wrong with it.

While writing this I'm preparing a windows RepairCD to see it that can help in any way.

So here I am to ask for help. Not an experienced Linux user at all so any help is appreciated.

Thanks in advance!

By this, can I presume that you used the AlongSide option to shrink Win8?

If so, you probably corrupted the Windows filesystem in the process, as that is known to be a typical problem when using Linux utilities to modify Windows filesystems.

What generally is needed to fix that is repairing the Windows filesystem using CHKDSK -- but there is no Linux equivalent for this.

The Windows Repair CD generally repairs only the boot loader files, but it might work -- so continue to prepare it.

Yes indeed. I think tutorials also recommended this method for dual boot?

I used the repairdisk to chkdsk. While it didn't find any bad sectors it seems, it did seemingly fix the problem as after running it, using update-grub again it managed to get windows to boot again :)

Thanks for the help.
