A quick googling of the 'security' message you're getting turns up the suggestion that there may be a security setting somewhere in the BIOS screens that is tied to the SSD in question and switching that off will let the BIOS choose another boot disk. Nothing to do with Windows, but a BIOS level security measure.

I've not come across such a BIOS myself but it seems the idea is that if you password BIOS access then even if someone steals your computer they will find it very hard to get at your data. This seems to be a common measure on tablets/laptops. It's the same principle as iPads erasing themselves if someone puts in the wrong password several times or tries to bypass the password and encryption using a PC.

thanks, tlw, a local repair shop gave me similar info ... there is definitely a BIOS security measure that blocks attempts to access disk when booting e.g. from Linux ...
 
so, eventually the tablet was taken apart and disk hooked up to another machine ... well, the disk is officially dead - so it was a coincidence that it died right at the windows update reboot ...
 
at least it's not any sort of "customized" SSD. I ordered a replacement of larger size so that this tablet hopefully can be restored to act as the live Sonar workhorse again (plus now with more storage I actually may be able to install some of the VSTi) ...

Well, when you do something than something goes wrong the logical place to start is to wonder whether the two things are connected.

And while putting a security system into the BIOS is a good idea, especially on anything portable, it would help if the purchaser was actually told about it in the manual. Not that much actually has a manual these days.

very true.
 
and "video killed the manual" ... just like video killed the radio star ...
