Windows 7: fixmbr - system repair disk

fixmbr - system repair disk

Hello,

I have a question related to the windows 7 bootloader.

I had some problems with the windows 7 bootloader after installing a linux os. Practically I couldn't boot into windows 7. I used a linux tool to repair the mbr. This installed a so called "generic compatible mbr", but not the original that windows came. Windows 7 works now properly...
Now, I wan't to delete linux, leaving windows 7 the only operating system.

What should I do in order to that. If I have no problems, it is recommended to replace the bootloader with the original one or leave it as it is?

Thanks in advance.

Lets have a look at the disk/partition layout first - this will determine the most practical method to use.

System Reserved partition has been cut out of booting Windows 7, it is now configured for C to boot (System) itself.

However I'm not sure why you have so many Primary partitions as you should be limited to 4 on an MBR disk. Perhaps Disk Mgmt is misreading the hidden Linux partitions.

To Dual BOot Linux easiest I'd follow the steps in these links: Dual boot Ubuntu-Win7
Dual Boot - Windows 7 and Linux - Windows 7 Forums

The tutorial's author Colin should be back to look it over for you, too.

@gregrocker: Thanks for reply. Those three partitions are actually linux logical partitions.
I thought of the same thing, but I wasn't sure...

I will read the tutorial.

There are two actually. The first is a link to a post by Barman58 which has helped many set up their Dual Boot perfectly over the years. The other is Colin's newer tutorial which also has good results.

Thats correct - Linux partitions show up as Primary Partitions when viewed in Windows Disk Management (example shown below):

Since the system files are on C: (meaning that Windows boots from C: and not System Reserved), the easiest method to remove Linux is simply to remove:

1. The System Reserved partition (it holds the Linux GRUB bootloader);
2. The Linux data EXT4 partition; and then
3. The Linux SWAP partition

I strongly recommend using the bootable version of Partition Wizard to do this, since the EXT4 and SWAP partitions are easily identifiable, minimizing the chance of deleting the incorrect partition (see Partition Wizard example below).

Once those partitions are removed, you can resize the remaining partition/s into the available free space.
