Dual Boot Windows and Fedora Reset

I am a student and recently stuck on a problem. I was successfully using dual boot (windows 8.1 and Fedora21 Linux) on my pc and last night I was trying to re-install windows 8.1 . While installation I was facing some issues and I accidently run these commands bootrec /fixMBR, bootrec /Fixboot , bootrec /rebuildBCD through command prompt in trouble shoot option. Later after restart , It didn't ask for boot option to select the operating system and now It directly boots to windows and doesn't ask/show the operating system list to load. I hope fedora is still in there and my notes are too. I tried searching out the internet but couldn't find the way to make it . Can I get the dual boot list again ?

You can boot with a Knoppix distro...

That will let you browse your drives and get your notes.  As long as they are there, you can copy them to a flash drive or USB HDD.

After that, run msconfig in windows 8.1 and click on the "Boot" tab and see if both of your boot options are there.  If not, you will have to probably start over from scratch and re-install both OSs like you did the first time.

But, the most important thing is to get your data first.

Knoppix can do that if the Fedora drive is still there.

Boot the PC from the fedora installation CD, it might have a tool included to fix GRUB. If it doesn't, check the PCRepix LiveDVD. It includes the "Grub Customizer". With it you should be able fix the GRUB entries and also reinstall it to the mbr of your HD with relative ease:

There are several tools that can repair grub.

Try boot-repair, SystemRescueCD or Rescatux.

Yes no need to reinstall the OSes -- just use one of the grub repair tools mentioned -- the commands you ran affected the grub boot loader but did not affect the installed OSes only the grub boot.

Thank you everybody for your expert opinions , especially thomas , lionel and rindi . I've got the boot list back through boot-repair live . But now boot-repair has made list like this.  http://prntscr.com/81gm9s , I don't know why linux 0 rescue and windows loader dev/sda2 there, both loads the operating system like rest of others.

Could be that your windows repair wrote the boot info to the other partition, so now you have two.

Is there any way to remove? And yes I'm seeing a system reserved partition of 100Mbs in my windows and it was not like that before.
rindiCommented:
You could use the GRUB customizer I mentioned earlier to edit out the entry you don't want. Another option would be to do it within Fedora. But I usually use Debian/Ubuntu based distro's, and I think Fedora has a slightly different location for their files, and another syntax to upgrade GRUB. If I'm not mistaken you would normally first edit the /etc/defaults/grub file and remove or comment out the part you don't need, and after that run the GRUB update tool of Fedora so this change gets written to the actual GRUB menu file.
Lionel MMSmall Business IT ConsultantCommented:
Go into Windows Computer Management, then disk management and see what partitions you have on your disk(s). The 100MB partition is usually set for "system reserved" and with no drive letter. The repairs you have tried to do has more than likely caused that. If you have only one 100MB partition then you can simply remove the drive letter.
