After installing the Alcohol Trial version it started causing BSODs (not only in alcohol, but in any DVD burning software that tried to access CD/DVD drives, ie. both Clone CD and Ashampoo also crashed whereas they worked before I installed Alcohol).
Therefore I uninstalled the Alcohol via the uninstaller, but the other software still crashed. I found out that I might need to also uninstall something called "SPTD". Therefore I downloaded the SPTD unintaller (otherwise there was no option in the system to uninstall it) and used it to uninstall the SPTD.
Since then, my Windows installation doesn't boot, always running into BSOD "BOOT DEVICE INACCESSIBLE" during the bootup. So far I wasn't albe to recover, as it doesn't boot even into the Safe Mode (still the same error). Also tried some repair option, Automatic Repair says it cannot repair, also no restore is possible because no restore is found. However in the repair command line the Windows files are visible and accessible on the disk (the main disk is SSD).
The OS version is Windows 10 Pro 64-bit 1903. The system boot seems to be damaged somehow. Does anyone know how to fix this, I REALLY REALLY don't want to reinstall the whole Windows and spend the next 7 days (to restore all apps and configuration) with it just because I dared to try out this software.
