WINDOWS 7 will not install on this hardware.

[techarchives259]

Toshiba u845w-

originally comes with win8; so naturally I changed Bios to legacy and installed windows 7... the laptop comes with a 32gb pci ssd and after win7 is loaded there is no room to even download updates, decided to order up a larger pci ssd to load windows 7 on and I have checked bios settting a ton of times and I now get 90% of install of win 7 and I get a "windows will not install on this hardware"....any clues?

I had windows installed with a 32bit win7 home and ive tried 64bit now but I cannot figure out what im missing...

The 32gb SSD is a caching drive meant to speed up the hard drive, but they are installed in a RAID that needs a driver which apparently is not in the 64 bit Win7 installer. Since 32 bit performs better for >4gb RAM installs I would boot it's installer to reinstall your licensed version.

We also have others who can help you if needed.

Sorry I somehow duplicated my first link so you didn't get to see SanDeep's tutorial here: Install Windows on System with MSATA and ISRT - Windows 7 Help Forums

Glad what was posted helped though. Did your reinstall 32 bit? Is the MSata in a RAID with IRST enabled?

installed 64bit on 128gb ssd, I installed raid drivers from Toshiba's site and then both hard drives showed up. I picked ssd and it installed fine.
