Today I was playing with TC 2.7 and 2.6.1 from USB, updating extensions, compiling, etc. Nothing special. No crash, no issues. Of course many reboots and halts. Later on had to work on Windows, so booted it normally from the HD. WINDOWS dis not start, and got the message, system corrupted. Its repair tool fixed the problem. No data or system got correpted, for sure it was just the boot.
I'm not using the machines HDD at all, did not use usbinstall, fdisk nor any other tool which is attaching the HD. Strange. I can not and to be honest do not want to reproduce.
It happened already two times before sometime in October but couldn't find any reason and issue did not repeated till now.
Any idea?
