how to mount HD disk0s2

Hi while i was installing Ubuntu from my external Harddrive i accidently unmounted my disk0s2 where i have installed Mac OS X 10.9 Mavericks

All my files in OSX are still good as i checked it in Ubuntu and Windows 7. I have a Ubuntu partition on a external HD and a Windows 7 partition on my MacBook Pro intern HD.

I tried to reinstall OSX in recovery mode but the App does not recognize the OSX partition which is disk0s2.

Disk utility in recovery mode does recognize disk0s2 however it is greyed out and it is not possible to repair it from there.

Disk utility says the mountig point of that drive is not activated and i can not activate the drive in disk utility either.

I tried to run diskwarrior 4.4 but it does not recognize the Hard drive either.

Physically the Drive is still good as well as i can still run my mac on Windows 7 and DW says the same.

When i boot the mac in fsck mode it spits out incorrect number of thread record (4, 26287) after i tried to mount the drive back through the Terminal App it said again incorrect number of thread records but this time with a (4, 22910).

I need to start from the Mac because i need to apply for university and all my resumes and certificates are in this partition. Unfortunately i have a very old backup without these file plus this backup is overseas and unreachable for me before the deadline ends.

Has anybody any kind of idea how t get to my OS back again.

i think i need to redo the /E mounting point and mount the disk0s2 to that mounting point again. i know it is possible through the Terminal App in recovery Mode but i have no idea how.

that does not work becuase Terminal then tries to mount the HD in /Volumes this means i only can read that Volume in other operating systems but not boot from it. I need to mount the HD in E:/ and i am not sure if this Mounting point still exists. This means i have to recreate Mounting Point E:/ and than tell terminal to mount the HD to exactly that Point.

No it didn't work either but i fixed the Problem.

I am explaining how so the next one reading this does not have that much problems with it

I produced a disk image of the Toshiba Hard drive which was still mounted and it gave me the files of both partitions back. After i produced a disk image of the Macintosh HD Partition through the other disk image. After opening that Disk image on my other OSX Partition that i set up on an external HD i was able to run the migrationasasisstant which migrated all my old files and setting. After this i just took the old HD out of the Mac and put the 1TB external HD back in. No my mac is having 1TB of storage and all my files a recovered.
