Why did you used a 3rd part software to split the boot disk, Windows have a build in tool under disk management to change the sizes and to add more partitions and safer than 3rd part tools and suspect the drive was encrypted before. I suspect the SSD is still good because it was working before you tried to spit the drive, the reason for the BIOS to be stuck because it is looking for a boot sector or MBR on the SSD but cant find it and can take some time to get into BIOS after pressing F2 or F12 to boot via a USB. If you can connect the SSD into another PC after boot and remove all partitions then your BIOS wont be stuck at boot. Juan
I have a Dell Vostro 3400 that has Windows 10 Pro installed and recently i use EaseUS Partition Master to split my NVMe SSD into half (it requires a reboot), and suddenly after the reboot it just stuck at Dell logo, i tried enter the BIOS but it also stuck too. I tried install another copy of Windows but it can't boot either. Can someone help?
