|I don't know how familiar you are with computers, but the PXE-E61 message means the laptop is attempting to boot off a network. This can mean one of 2 things: either the boot order is incorrect (possibly due to a bad CMOS battery) or the hard drive is bad (or there is no hard drive installed).|
The 1st thing to do would be to enter the BIOS & check to see if a hard drive is being detected or not. If it is, check the boot order to make sure the hard drive is listed before the network. If it's possible, just disable the network boot option altogether. Also, check the date/time. If it's reset to a date in 2003, the CMOS battery needs replacing.
