Both screen shots in post 31 are saying that your hard drives are not detected as a boot source. Since there is no boot source on the DVD drive, it is going to the next item available on the list, the network card.
Ok thanks that's useful.
I'll list it here:
Both HDs show up immediately and work fine as external drives on my desktop pc with a USB adapter. They also both show up in BIOS. I've burned a W7 Home 64 dvd (twice) from the link in post #19.
1) With original HD, and said W7 install dvd in optical drive. At power on, It immediately flashes the normal bios screen (or whatever it's called) as it should. Then it takes 3 minuets of black screen. Then flashes briefly the first error scrren in post #31. Then goes to black again for another three minutes. Then gives the second error screen in post #31. No matter which option I choose at that point it will just loop again into one of the former menus and just keep repeating the same pattern. For example, selecting boot menu number one DVD drive, will just make me wait three minutes and then show the first error screen and post 31 again.and repeat.
2) spare HD with said W7 dvd in optical drive. As above, gives first then second error screens. Except does it much faster, all with a few seconds. Also, it lists the HD as "boot menu" option "2" (the PCI LAN thing is bumped to option "3"). So at this screen it appears to detect the spare HD , but not the original HD . However, it will also loop back through these two error screens if I press enter on boot option 1 (dvd drive). So I can't install the W7 dvd.
Is this dvd ok?
As a side, Ive attempted to use the w7 on my desktop to install/repair. It's a different version than the laptops "Home" edition, so if I do get it working won't work with the key. It's on SD card, so I changed bios boot order, it's recognized immediately. But it also loops, kicking us to this screen:
At this point, is my hunch correct, and some hardware on the MB is toast?
Lenovo customer service is worse than nonexistent- they wanted to transfer us to talk to a technician over the phone - and start at 40$ for that call.
Perhaps The most efficient route would be to try and find an identical laptop used, put the original drive in it, and then we have a bunch of usable spare parts as well.this may be challenging to find, are there any other models that would be sure to work with this hard drive installation and all the drivers as is?or would it be best to toss the lot and just start with a brand-new laptop?
