GRUB not allows to run acer recovery

[dh_electro]

Hi

I have installed Ubantu on my ACER 5720. I am using grub bootloader. now I want to install windows vista on my laptop. So I tried to run acer recovery CD after running this CD I am getting GRUB 22 error.
So I want to remove grub and want to put windows bootloader back so it can load window. Please let me know if you have any experience of this problem.
Here is my fdisk -l

Welcome to the forums dh_electro

The easiest way is to use SuperGrub to restore Windows booloader to MBR.

Hi Jonathan,

I have made supergrub CD. I managed to see Grub loader. But when I put my ACER recovery CD. The window vista displays massage No Partition found though I have more then 90 GB NTFS partition.
Any idea how to solve this problem..

Thanks
Dhaval

If you are sure that you restored Windows bootloader code to the MBR then your problem is likely to be caused by one of two factors:-
1. you deleted the recovery partition which Acer installed before they shipped the system (my Acer laptop when first shipped had an Acer recovery partition plus a Windows Vista partition).
2. sometimes Windows refuses to boot unless it is the first partition on the first hard drive.

I suspect the problem is to do with the recovery partition being removed.

First backup all user data then I suggest you take a copy of the relevant files on the Windows partition relating to activation and then run the install from the recovery CD Acer supplied. I managed to get Vista to boot that way after I removed partitions. I no longer use Vista so can't get further info on this anymore

I posted some info on activation on the forums I'll search and add link here.

Your fdisk output doesn't show any recovery partition and you have one ntfs (windows) partition on sda6 which is a logical partition. xp won't boot from a logical partition unless there is a windows OS (or at least boot files) on a primary partition.
