Jude’s Windows 7 computer won’t boot
I have a Toshiba netbook with windows starter edition. Suddenly It stop booting up. The Toshiba screen comes up then I get an error message saying boot manager is missing. I can press F2 and it works to get settings but no restore option. Since there is no cd tray can I try a repair using a usb. How would I create a repair program on a usb? Thanks for any help.

Hi Jude. Assuming you already have an empty 4GB (or larger) USB Flash Drive, The first thing your need to do (if you have access to another computer with high-speed Internet) is to download Windows 7 (ISO) file from following link(s):
32-bit Windows 7 Home Premium
http://msft.digitalrivercontent.net/win/X17-24208.iso
64-bit Windows 7 Home Premium
http://msft.digitalrivercontent.net/win/X17-24209.iso
If you’re not sure which one to download — choose the 64-bit since a majority of Windows 7 installations are 64-bit.
Next download the Microsoft Windows 7 USB/DVD download tool

After you’ve downloaded the ISO file, copy the Windows 7 ISO file on your USB and, run the Windows 7 USB/DVD Download Tool. After you do this, you can boot into Windows 7 computer directly from the USB flash drive.
To boot from the flash drive you created, with the USB still in the USB port, shut your computer down and wait 60 seconds, then power it back on — you should see the option to boot from the flash drive appear on your screen. Select that option.
Once you’ve booted up you should see several options –one of which is to “Repair your computer”. Choose that option. In the System Recovery Options dialog box, click Command Prompt. Then type Bootrec.exe, and then press ENTER.
Use the Bootrec.exe tool to troubleshoot “Bootmgr Is Missing” issue. If rebuilding the BCD does not resolve the startup issue, you can export and delete the BCD, and then run this option again. By doing this, you make sure that the BCD is completely rebuilt.
To do this, type the following commands at the Windows command prompt (press Enter after each command):
bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd
Hopefully, you won’t have to run all those commands to rebuild your Boot Manager, Bootrec.exe should fix your problems automatically. But, just in case, we’ve added them for you.
Good luck, Jude
