Dual Boot Doesn't shows

[stellar]

I have 3 HDD, 1 PATA and 2 SATA HDD. I have installed previously windows 7 in pata and my 1 sata got corrupted so i got it after repair. Nd i deleted windows 8 and i installed windows 8 in new HDD. But after i did that the dual boot option doesn't comes. I thought there must be some error so i formatted the pata hdd and reinstalled win 7 but again no dual boot option. I think my problem is the previous hdd which i installed win 8 but i formatted it. how can i get back dual boot option?

Use Easybcd to create boot records, if you're sure where you installed your OS's.

Install EasyBCD freeware on your default OS and Setup multi boot option from there in.

EasyBCD is no longer freeware, but a Shareware. Although free for non commercial use and can be download only after you "Register" at their website. But worth the hassle, since its the best tool out there to fix boot entries.
