usage: fdisk [-ieu] [-f mbrboot] [-c cyl -h head -s sect] [-S size] [-r] [-a style] disk

-bash-3.2#

when OSx wants to boot , the porhibited sign will comes up

when I use disk utility in online recovery to repair disk, it will show problem with partition map table prevent boot.

and when I get option key, it will shows up

thanks, please save me

I wanted to convert GPT to MBR using gdisk, and when I write to partitions, using expert and then n and w, after boot up the problem comes up.

can i use time machine from online recovery, to back up my stuff ? and do the upgrade ?

I must mention that, I'm able to boot into a live Gparted USB to use the testDisk and gdisk, if there is a way to recover the partition map tabel

the problem comes out when it was creating new protective MBR and when it was trying to write to partition table, it couldn't finish the operation.

I do have a external hard drive, But i have to transfer all the data on, into another PC first.

how to disable FileVault2 ?

alright, I install new Os x on my external hard drive and i can access to my MachintochHD , I can see my files as well, should I back up it and Install new Os x on my internal hard drive or am i able to fix the partition map?

I disable FileVault as well

here is the output
