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!

Default Boot Device Missing fix?

Hello Rumen, sorry about your problems. My name is Marco and I will do my best to help you.

The error messages you are seeing suggest that the laptop is unable to find a bootable device, which could be due to a misconfiguration in the BIOS/UEFI or a hardware issue with the storage device.

Turn off your laptop completely.

Press the power button to turn on the laptop.

Immediately start pressing the F2 key repeatedly to enter the BIOS setup.

Once you are in the BIOS/UEFI settings:

-Check the boot order to ensure that the internal hard drive or SSD is listed as the first boot device.

-Look for any settings related to storage or SATA configuration and make sure they are set correctly.

-If you see an option to load default settings (often F9), you might want to try that to reset the BIOS settings to their defaults, which can sometimes resolve boot issues.

If the storage device is not listed or if these steps do not resolve the issue, the storage device may have failed or become disconnected. In this case, you may need to contact Lenovo support or consider returning the laptop for service.
