Missing operating system after merging two parttions

Hello sevenforums!Sorry for posting same post in BSOD HELP ANd SUPPORT category thought it was generally for help.I searched for an answer but with no luck.I have an ASUS laptop with i5 windows 7 service pack1 and hdd 574gb as it says.When i went to disk management i saw a partition or volume (do not know the exact difference) with 21,49gb free(unallocated i think) and thought to merge it with c: where windows 7 were loaded.The partition with windows were at the right from the other partition with 21,49gb and could not extend volume.So i downloaded AOMEI and merged them, as i did one day before in another pc successfully.But now when starting pc says missing operating system.I did bootrec /fixmbr and bootrec /fixboot (without the command bootrec /rebuildbcd be aware something goes wrong as it did) with the windows cd but nothing.If set with diskpart command partition active or primary will fix the problem?I burned gparted live but what should be my next step?Do i have to make two partitions again?Move unallocated partition to the right if there are two?Or what to do without losing my data and not reinstalling windows?PLEASE HELP.Its laptop for my work.Thanks in advance!

Welcome to the forum. Can you get a screenshot of the disk partitions so we can see? Is your system MBR or gpt disk and do you have a small boot partition?

Today when i opened laptop mbr is missing do not why.With installation disc opened cmd and here the results:

command list volume : volume 1 letter c system file raw size 574gb

command list partition : *partition 1 size 574gb relocation 21gb

command list disk : *disk 0 size 596gb free space 21gb

As i opened aomei and easeus saw this:
Missing operating system after merging two parttions-partitions.jpg
That means the merge never completed dont know wasnt in front of the pc.
But what about raw, is the system file for unallocated space?The partition i care about is NTFS AND active why is unbootable?I am moving with AOMEI THE unallocated space to the right will it have some result or no?But it seems to be stucked 14%

Not my area but i can tell you this.

Looks like your trying to boot from disk 2, its first partition is marked as Logical, W7 CANNOT boot from this type of partition.

Check your BIOS select disc 1 as primary option.

I am not a phone so I can't see photo very well. Disk 0 has a recovery partition and a system reserve which as explained is were Windows boots from not drive c so it should be active. Drive 1 had a small unallocated partition which would have been were Windows boots from. So without that Windows can't boot.
If you want to boot disk 0 unplug disk 1 so it doesn't confuse the issue
