Anyway,
If for any reason you have the same problem, the way to fix it is the following:
1. Boot your computer from Windows Installation DVD.
2. Select the “Repair computer” option.
3. Exit the wizard by clicking “Cancel”. This will take you a menu with various options.
4. Click “Command Prompt” in the menu.
5. Here you should switch to your DVD Drive. If you are not sure which is the DVD drive letter, you could experiment by trying each one of them, or you could use the DISKPART command and then LIST VOL which it will give you a list of all drives on your pc, similar to this:
Microsoft DiskPart version 6.1.7601

On computer: ADAMOS
DISKPART> LIST VOL Volume ### Ltr Label Fs Type Size Status Info ———- — ———– —– ———- ——- ——— ——– Volume 0 E CD_ROM CDFS DVD-ROM 3562 MB Healthy Volume 1 F DVD-ROM 0 B No Media Volume 2 H DVD-ROM 0 B No Media Volume 3 System Rese NTFS Partition 100 MB Healthy System Volume 4 C NTFS Partition 254 GB Healthy Boot Volume 5 D Data Volume NTFS Partition 196 GB Healthy Volume 6 Recovery NTFS Partition 14 GB Healthy Hidden Volume 7 I Prestigio D NTFS Partition 465 GB Healthy DISKPART>
Exit DISKPART by typing EXIT and ENTER.
6. Now, assuming that your Windows 7 is installed on your C: drive and your DVD-Rom drive is E:, type this:
COPY E:\BOOTMGR C:\ and press ENTER.
7. Make sure that the BOOTMGR exists on your C:\
8. Type EXIT and press ENTER.
9. Select RESTART from the GUI menu.
And that’s it. Your computer should be able to boot normally and start Windows!
