How to download AMD VGA drivers for Lenovo B50-70?

Hello,



Thank you for writing to Microsoft Community Forums.



1. Which version of Windows are you currently using?
(To check the operating system information, you can refer this article on
Which Windows operating system am I running?)

2. Are you aware of any changes made on your PC recently?



This issue can occur if there is a hardware issue or if the respective drivers are not installed on your system. If you are using Windows 10 on your Lenovo B50-70, I suggest you to download the drivers from the manufacturer’s website and
install it on your PC. Use the following link to download
AMD VGA Driver for Lenovo B50-70 and check if it works for you.



Hope it helps.

usb first boot

When you say it is not in the List, do you mean the USB drive is not in the list, was the USB drive plugged in at the time?

In order for a drive to appear in the boot list it must be plugged in before you enter BIOS and sometimes you might need to move it to another USB port and enter BIOS again for it to appear in the list - I had this issue on a Lenovo before . . .

 

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!
