Windows 10: No Bootable Device

I have an Acer Aspire Laptop running on Windows 10 with a 950GB C drive and I was having fun playing train simulator until my pc just committed suicide and it first started off with blue screens of death occurring 24/7. Then an error message showed up saying "A required device isn't connected or cannot be accessed" and it wouldn't take me to windows . Now when i boot my pc, "No bootable device" shows up and I can't access it anymore. i tried different methods like pressing F2 when the Acer logo appeared then entering the BIOS settings and etc. But that didn't work. i tried the method on Acer's YouTube channel but that didn't work either . I don't know what to do with my pc anymore because I don't have a Windows installation DVD or USB and I don't have any screwdrivers to unscrew my laptop and take out the battery then put it back in. I am just about to give up this is so frustrating I've tried for so long now my computer has not been working properly since August. August was the last time it was working properly why this always happens when I get a Pc it just committs suicide ���.

Multi-bootable USB

Hey guys from TPU, couldn't find any specific thread pertaining to the question asked on title. As mentioned, I'm trying to create a bootable USB, but with many specifics boots available.

I've been trying to create one with multiple boot device including one that enables me to run Windows 10 directly on the USB Thumb Drive but to no avail.

The list of bootable images i'm trying to create are

1. Windows 10 (A full OS running from thumb drive)
2. Windows 10 ISO (Bootable disk image for fresh install)
3. MemTest86+

Have tried YUMI or UUI from the website USB PenDrive Linux but as this is my first time, i don't know how am i screwing up or am doing it right.. Anyone got a rough idea on a step by step guide? Thanks!
