Recently I spent too much time attempting to load Win7 on a Toshiba Satellite L875d-S7332. The HDD was replaced with a new WD and the 64 bit install DVD set to boot. The installation start froze at the windows welcome screen. I tried a dozen different CD/DVD for win XP pro/home, win7 upgrade, win7 new install.... All failed. Even the falconfour bootdisk would not launch. BTW the BIOS security was disabled. My next attempt was to install win8 on this HDD and the win8 DVD was recognized and booted! Win8 loaded up, then I tried to install win7 pro from win8. The win7 DVD autolaunched! Everything seemed to go well until the next boot and again the system froze at the welcome screen.

So after three hours of failed attempts I ask these questions. Has Toshiba built a Win8 only system? A BIOS that will not recognize boot sectors other than win8 dvd's? Or is this a Microsoft lock device?

As a consultant for small business, I cannot recommend my clients buy new computers with win8. I hope MS comes up with an option to return to convention START button menus soon!!! Until then I'm looking for a win7 theme and navigation scheme for win8 devices.

Does your Toshiba have a UEFI bios or a normal bios?

UEFI bios do not like booting from CD's or DVD's, especially ones that don't have a EFI dedicated folder. This isn't an issue because optical media is dying anyways.
UEFI doesn't like DVD's or CD's that most manufactures disabled CD/DVD booting for UEFI Boot and instead added a
legacy option to boot from a MBR instead of a GUI.

I'm only saying this because Microsoft is requiring all OEMS to use a UEFI bios instead of the legacy BIOS.

And remember, UEFI uses a GUI, a partition with boot files, not an MBR that reads the first sector.

My best bet is to try booting from a flash drive.

Update: I recently bought a laptop from Best Buy on black friday. A lenovo. It came with the UEFI bios and I wanted to dual boot Windows and Ubuntu. I do have a legacy option but wanted to teach myself more about UEFI booting. So, after failed attempts with booting from the cd/dvd, I put the installation on a flash drive and it worked perfectly.

The neat thing about UEFI is that in the UEFI BIOS settings you can control which bootloader boots first. I find that easier than rewriting the MBR everytime I want to change bootloaders.
UEFI is quite old, but has been improved enough to be practical, replacing the legacy BIOS.
