Windows 8 Laptop will not boot from DVD

By tjharring ·
I was formally the IT guy for a small company. To date myself, the last network OS I worked with was Netware 5. The problem I am having is trying to downgrade from Windows 8 Pro to Windows 7 Pro.

Okay should be a piece of cake, but it's not. I recently purchased a Toshiba P850 series laptop. My intention from the very beginning was to downgrade. I do have a Windows 7 pro dvd, the laptop is configured to use the ODD drive as primary boot. When I boot the system it continuously boots from the HDD. I have spent time on the phone with Toshiba's tech support, but that was a waste of time. Much to my dismay Toshiba's tech support is sorely lacking.

During on of my calls I was transferred to Toshiba's, "Expert support" who told me to use the Shift + Restart function to be able to boot from the ODD. I was told this must be done because even shutting down Windows 8 only puts it into an advanced hibernation. I have tried the shift + restart option that brings me to the advanced start page. According to tech support I am to choose "Continue on to OS" and when screen goes black hold down the F12 key.

This does the exact same thing as holding down F12 after power on. I brings up the boot manager to select your primary boot drive. In any case I cannot boot from the ODD. Does anyone have any ideas?

couple of thoughts

by Sue T In reply to Windows 8 Laptop will not ...

on some of our toshibas there is a program called hwsetup and I have to actually change the boot order in that to make it work. Also, some brands of laptops also have in the bios a quickboot option that you have to disable. might be called something else if present. can you go into power options in windows 8 and disable hibernation and change the power key to mean shutdown?
Good luck. As I have some toshibas I will be interested in the outcome.

The answer to my problem was in the BIOS, something Toshiba's techies did not know. I had to disable "Secure Boot" and switch from booting with "UEFI" to "CSM". Once this was done system booted from the Windows 7 DVD. It is now running on Windows 7 and I just need to find two more Win7 drivers and I'm good to go. Surprisingly the BIOS was configured for normal boot not fast. Sue T thanks for your response. I decided to go through the BIOS configuration first before altering the power settings.

Finally! A solution! Turning off secure boot and changing UEFI to CSM worked a treat. Thank you very much for posting your solution.

Don't think I'll be advising clients to purchase a Toshiba from here on out. That was a complete waste of my time for absolutely no reason.

Optical Disk Drive. It used to be easy to say CD, but the disks come in more flavors now.

Many thanks FlavourNugget.
My first post and your reply was not visible when I logged in 2 hours later,
and I thought I must have clicked Cancel when I intended Submit,
hence my second post.

I am now guessing there is a 2 hour wait for moderator approval before a post appears.

Incidentally I ticked the box to be alerted but have not yet got an email.
