UBCD- Interesting "feature"...

[Xernicus]

Now this isn't the first time I've noticed this, but this the only time it's really freaked me out

        So for a long time now I've been meaning to clean out my daily driver desktop (my ol' girl ) and replace the heatsink compound. Unfortunately for me, I use a weird design cooler (though it's super effective! ) and I skipped the manual altogether and had to re-apply the heatsink compound twice- both were my fault first time, I lifted the cooler and created an air pocket and the second was because I didn't apply enough... I have done this hundreds of times and only mess up on my PC. *sigh*
        
Anyways, to the actual problem...
I use the Ultimate Boot CD (UBCD) quite often to run diagnostics. (I've been meaning to create a custom diagnostics suite for a long time, but I seriously don't have the time) All of the tools work well for me except for Parted Magic, which never works on any PC I've tried, and I don't use/like it anyway, but specifically on my desktop PC when I reboot from the UBCD, my computer won't boot off of the hard drive, and bootloops (POST -> Specs screen, SMART status, DMI update check -> Reboot) It doesn't matter if it reboots, or I hit ctrl+alt+del, or if I power it off. The only way to fix this problem is to flick the power switch on my PSU, which is the equivalent of unplugging it (both work). After that, my PC boots and works normally.

I'm wondering if anybody else has this issue. I'm pretty sure it's a software issue with the UBCD since that's the only thing that causes it, but it is awfully odd.

So far I never ever encountered such an issue with UBCD.. In all cases, never with the 5.3.1 (which is the latest I used and the latest iso I have on my pc) and the preceding versions. I see that they released 4 versions more, so maybe an issue with the latest release (5.3.5). Have you tried another version?
