DualBoot Backtrack5R3/Windows8 start ERROR

Hello Friends,

I have a SONY-Vaio-SVE1512E6EB-Laptop. Yesterday i made a Bakctrack5R3-KDE-64bit-iso -LiveCD. I changed the boot-option from UEFI to Legacy , so i could boot the iso-Live-CD. When I booted in Backtrack I wanted to install it. I choosed "Install them bide by side, choosing between them each startup". For Backtrack I gave 50 GB. Everything worked perfect. I rebooted and there appeared 6 items to choose:

Code:

---

Ubuntu, with Linux 3.2.6
Ubuntu, with Linux 3.2.6 (recovery mode)
Memory test (memtest 86+)
Memory test (memtest 86+, serial console 115200)
Windows Vista (loader)(on/dev/sda2)
Windows Vista (loader)(on/dev/sda3)

Is there any way to get my new Windows 8 back? It makes me really sad, when I think about, that my Windows 8 might be lost:( I have a few high-payed Licence-Programs like Microsoft-Office-2010 on it.


Thank you so much for your help,

Ben
