Re: Bootmgr is missing no OS in System Recovery options
It sounds like your hard drive is toast. If you want to be absolutely certain, download and burn Dell Diagnostics to a CD and boot off the CD.
Otherwise, buy a new hard drive and install Windows Vista Home Basic to it. Be sure to download drivers for your laptop beforehand and save the drivers to a USB stick. You will also need to read http://support.dell.com/support/topics/global.aspx/support/kcs/document?c=us&l=en&s=gen&docid=DSN_1A...
As for trying to recover data files from your old hard drive, buy http://www.newegg.com/Product/Product.aspx?Item=N82E16812156102
