Can't access windows back after extending primary drive

Dell / Inspiron n5010
March 4, 2012 at 12:56:59
Specs: Linux x86_64) and Windows 7, 2.528 GHz / 3958 MB
I uninstalled ubuntu 10.04 present on one of my partitions and tried to merge it back to the primary partition. I used Partition Magic in order to do that. The already existing Windows 7 Home Premium was not touched at all, so I assume nothing happened to those system files in the process of deleting partition containing ubuntu. Total 69 GB of space was freed.
Now on rebooting the computer didn't start. Instead it restarted as soon as windows logo half appeared.

Then I tried using a windows 7 "home Basic" (due to absence of Home premium disk) disk to fix errors, but all options (including system restore) displayed errors and didn't start. When I chose "custom install" option the initial primary drive of 386 GB size didn't show at all as the options to put OS into. Instead the 10GB recovery drive and 69GB freed space showed up. I formatted it and installed the whole of windows 7 Home Basic on that 10GB partition.
Now the computer started on windows 7 Home Basic and still in the "My Computer" there was no initial primary drive of 386 GB was listed.
I went to "Disk Management" option in control panel and there the 386 GB partition was listed normally. Other than that somehow the 69 GB free space was mentioned as a logical drive, Now believing that it contained all the system files and boot manager, i marked that 386 GB partition as active, cleared that 69 GB space again and restarted the computer.

Now the the system doesn't start and instead it says "BOOTMGR is missing".

Also booting using Windows 7 Home "Premium" (arranged later on) shows no already existing OS present.
It also doesn't show the 386GB partition.

How could I proceed?

You really made a mess of things. See if this helps:

Next time you want to experiment with Ubuntu (or Ubuntu based distros), try using the built-in WUBI installer.

With the Home Premium disk, do you get the option of a Start Up Repair?

Partition Magic is OLD - the last version of 8.x was released in ~ 2001 - and it's NOT Vista or Windows 7 "aware" (compatible).
Amongst other things, Vista and Windows 7 use a slightly different version of NTFS software partitioning than that used by previous Windows versions, that Partition Magic cannot "understand" properly. (You can avoid that particular problem if you make all NTFS partitions with a Windows version previous to Vista.)
When you try to install Partition Magic 8.x in Vista you get a message saying Partition Magic is not compatible with Vista. That probably applies to Windows 7 too.

In your case after what you've done, you probably need to DELETE any partition that was modified by Partition Magic, then install Windows 7 from scratch !
....

If you want to use a "partition manipulation" program to increase or reduce the size of a NTFS partition that was made by Vista or Windows 7, whatever you use must be Vista or Windows 7 "aware" (compatible).
E.g.
This IS ....
The freeware Easeus Partition Master Home Edition can be installed in Windows, but only the paid version can make you a bootable version of the program to boot your computer from.

You COULD have (not now of course) just used Disk Manager within Windows 7 to delete the partition and expand your C drive or just create a new Widows partition. NOW, I agree, I believe you WILL end up reinstalling from scratch. You MAY be able to access to save files from a Live Linux disk if you do not have a comprehensive current back up already, but you will have to try it to see if it will work.

Vista and Windows 7 has the built in ability to expand an existing partition (if there is un-allocated space available on the same physical hard drive adjacent to and before or after the partiion), or contract an existing partition, without losing the data on the partition, but documentation about how to use that feature is hard to find.
It's much easier to use a third party program such as Easeus Partition Master Home Edition.

What documentation do you need? You just open Disk Management, right click on the partition and select 'expand', then the wizard opens and you enter the amount you want to expand it by. Within a number of seconds it is done.
Is it just me, or is that not easy?

I found the HELP documentation about how to use the built ability of Vista to expand - EXTEND - or contract - SHRINK - an existing partition without losing the data on the partition.
The same probably applies to Windows 7.

It's NOT in Help and Support (at least it isn't in Vista) - it's in Disk Management's Help.

In Vista....
Control Panel - Classic View - Administrative Tools - Computer Management - Disk Management

In Windows 7......
Control Panel - display as Large icons or Small icons - Administrative Tools - Computer Management - Disk Management

RIGHT click on the drive letter of the existing partition, click on Help.

Choose

Manage Basic Volumes

Extend a Basic Volume

or

Shrink a Basic Volume

Use a partition Manager Tool to fix this problem.
you can also try it manually by following these steps:
Windows 7:

Right Click My Computer | Manage | Disk Management

Right Click on existing partition, Click on Help
Choose
Manage Basic Volumes
Extend a Basic Volume
or
Shrink a Basic Volume

Hope it fix problem you faced.
