Bootloader missing after USB install

Question

I've tried to install Ubuntu 12.04 from USB following the official instructions I created the USB key and started the install.

I chose to install Ubuntu alongside Windows and kept the suggested partitioning scheme.

At the end of the install I rebooted and the bootloader is not there and Windows boots.

I have tried with both Universal USB Installer (suggested on the Ubuntu site) and with Unetbootin.

Please run boot info script bootinfoscript.sourceforge.net and post the RESULTS.txt which it produces.
Thanks for trying to help but I've since lost patience and nuked all other partitions and I'm installing Ubuntu alone. Hopefully this time it will work.

Put windows disk and click on Repair. Start command prompt

Type

Bootrec.exe/fixmbr
Bootrec.exe/fixboot

You should get your Bootloader back.

Edit In case you don't have installation media:

You can download recovery disk from your Manufacturer.
You can download , master boot record disk and use it to repair boot record.
You can do complete system backup using your Backup Drive. ( Provided as recovery disk from manufacturer.)

	Unfortunately I don't have any Windows media: it came preinstalled on my Lenovo laptop. What alternatives do I have? – L. De Leo Jun 17 '12 at 13:58
