    Interesting. I'm also on a Toshiba laptop. I think I will try installing on my HDD.

    If the installation didn't complete, none of the Windows 8 repair options will help right?
    Also, (may be a really silly questions), but at what point do you actually remove the Windows 8 Installation disc from the computer and change your BIOS back to boot from HDD? I would assume not until you reach the Windows 8 desktop?

    You don't even have to change anything in the bios setup itself. Look for the F key like F4, F8, F11, F12 for bringing up the boot device menu when going to boot from th 8 dvd. You then select th cd rom option.

    Once the first restart is seen once all setup files are copied over you will be booting from your main drive right away! That's when you will run into the new Setup Wizard full of screens which is quite a bit different as most are now aware of!

    As far as the Automatic Repair option if the install is incomplete you wouldn't expect it to be any good. That is for repair of Windows once you have it up and running and then something stuffs up on you preventling Windows from starting or running right.

    These may or may not help you. Not sure there is a solution for it yet.
    So at what point did you realise it didn't work with just your laptop screen? Obviously the installation was successful, but how far through it did you get before you thought it didn't work?

    Thank you! I may have been going wrong there by changing to boot from CD Drive in the bios.

    Interesting reading all this...
    I'm on an Acer laptop and I just can not get it to boot cleanly. Although both OS's work (W8 and Vista) it's a case of forced shutdowns and reboots to get to one or the other.

    I looked at and went through the repair options a couple of days ago but no luck.

    Generally you should see a normal boot from any installation disk either way. The F key to bring up boot device menu however simplifies the task of making repeat trips into the bios unnecessary and often prevents forgetfulness of leaving it set for the optical drive and then wondering why the installation isn't proceeding along as it should?

    Too often I hear people complaining they can't get past a certain point with any installation and wonder why they end up in a loop. If they pulled the install dvd out too soon as soon as all setup files are unpacked to the drive but forget to go back into the bios they end up with a loop!

    As for your problem there Mooly it sounds like the boot configuration isn't correct. If you are using the entry for Vista found in the 8 boot menu following the install and Vista refuses to load up you may have to remove that entry and use a 3rd party tool. Here with a dual boot across two drives the 7 entry added into 8 was automatic while the one for 8 added into the 7 BCD required the new version's Advanced Repair option in order to 8 load when selected.

    Each drive ended up with the option to boot into the other version regardless of which drive was set as the default boot device. All this was part of testing the 8 boot loader. Likewise with Vista you may have to run the EasyBCD tool to add an entry into one version for the other as well as run the Vista Startup repair if it refuses to load when selecting the older version when leaving 8 as the default OS.

    The 2.0.2 version or newer is advised for 8 while you can go back as far as the 1.5.2 version for Vista since it was developed for Vista from the start and later updated for 7 and now will be continually for 8. Without a second HD in your laptop you are kind of left in an awkward spot since you can't isolate one Windows installation from the other as far as mbr entries and boot information on two separate drives. The newer version wants to charge automatically.

    Another thing to mention is that Windows regardless of which version it is always prefers the first primary on the drive it will be installed onto! Now add the OEM factor with things like the recovery partition as well as the factory preinstall's own boot information. There's just enough of a change seen with the 8 BCD and boot sector info to throw things in a whirl at times over the close compatibility Vista and 7 shared with each of their own BCDs.

    Thanks Night Hawk. I do have a recovery partition (XP never to be used again) so as you say the OEM configuration could be an issue as well. Vista was clean installed using the "free upgrade disc" at the time.

    I'm a seasoned Acronis user and so I might have another go at clean installing W8 as main OS for a play knowing I can revert back all partitions as they were at any time.

    Thanks

    Still having an issue with getting W8 to display on my laptop's monitor...Oh, and when I do get on W8 (when I connect it to my TV), I connected to my windows live account. But, when I type in my password, it says I get it wrong...I've tried many times, too.

    If you have a keyboard without a seperate nums pad, check whether the nums lock is on. That would alter your password.
