My last hope -> the USB Recovery Creator by Lenovo. I tried everything : Repair function via USB stick Startup help via USB stick switchting between UEFI/Legacy Mode and other BIOS tweaks (turned fast + secure boot) Re-installed (~5 times) and tried several (ALL) CMD things with diskpart. The installation was done and I had to restard the laptop: 'Default Boot Device Missing or Boot failed' - my misery began and I searched the web, unfortunately without any success. I did this a lot of times before and was usually done within an hour max - not this time. So I removed the HDD (WD 1TB factory built int), put in the SSD (SanDisk 480GB) and installed Windows10 via USB Stick. I upgraded the laptop (Lenovo Ideapad 110) of my father in Law with a SSD. Honestly this is the first time in years asking for advice on a forum, so I hope you guys can help me :).
