This Vaio does have the UEFI "Unified Extensible Firmware Interface" designed by Insyde-

I'm pretty sure that it's in this hidden partition.
I could be wrong but (I think) somehow the UEFI system partition prevented the install somehow.

I have also found out the hard way that the new BIOS prevent a distribution from installing because of a key that is needed. My old desktop w/o UEFI BIOS excepted all 6 Linux distro's that I tried.
But with my machine that has the UEFI BIOS I was only able to install Ubuntu or Fedora.
All other Linux Live DVD's failed to install and locked up.

I do remember the Slackware installer making mention; in regard to the power adapter not being recognized. Sorry I don't remember the message.

I will attempt a fresh install of Slackware again and see if the results are the same.

Another thought is that the iso files that I burned on DVD were corrupt-
The orginal machine that downloaded that iso is down now but I do not have evidence to support that it was the iso files that caused it-
I'm working on that-

Hmmmm doesn't the management at Microsoft understand that if they manage to gobble up that last little remaining...what? 6-8% of the desktop market and put all competition out of business that they won't have anyone to steal from anymore? Just how greedy must one be to have 93% of the pie and can't take your eyes off the remaining sliver?

Good luck with your future install

Thanks!-

That partition has nothing to do with UEFI, it looks more like a partition that is used for Windows recovery.
Also, what you speak about possibly preventing your system from boot would be Secure Boot, not UEFI. The fact that you were able to boot from the install DVD of Slackware and that you have Windows 7 installed, which doesn't support Secure Boot, tells us that it is not activated, if your UEFI even has it implemented.

Microsoft is not preventing anyone from installing Linux. Secure Boot is a security measure that can also be used by Linux systems. Furthermore, Microsoft only allows hardware manufacturer's to use the Windows 8 logo if there is an option to disable Secure Boot and if there is an option to add your own personal keys to the firmware.

Yeah, Toby, I know but I am not about to pass up a chance to get some digs in. Ballmer called Linux a virus. 'nuff said.

I didn't say anything but I also doubted that the partition had anything to do with UEFI. While there does exist such a thing as UEFI partitions, the base rules are all onboard the motherboard as firmware, similar to bios but much bigger ie: BIOS is/was based on the ancient 16bit 8088, and can only directly address 1MB. However, the only UEFI box I have runs in bios compatibilty mode. I presently have no need of all the extensions UEFI has provided so far.

By "not activated" do you mean that in my BIOS something is not either enabled or disabled?

I'll have to go into the BIOS and see to know for sure.

Hi,

I agree with TobiSGD on this issue. Too much FUD out there for 'Secure boot', EFI & 'UEFI'. If you can boot then your do not have a 'Secure Boot' for a default BIOS. If you do have a 'UEFI' BIOS then you will have an option to use 'BIOS' compatibility mode. Plus as a user with 'UEFI' you do have the option to disable 'Secure Boot'. A must to allow changes for the system with MS.

What I mean is: If you have Secure Boot in your UEFI firmware at all (none of my UEFI systems has, they are simply older than Secure Boot) then it is disabled, otherwise you could neither boot Windows 7 nor the Slackware install DVD.

Acknowledged!-

And what you've said confirms that the only other thing the problem was in my case was the lack of understanding the installer that came with Slackware. Operator error:-

With the fear, uncertainty and doubt you hit a home run on that! onebuck!-

That's for the confirmation in your above sentence about compatibility mode--
