Hello, I fixed it real good. I bought a Lenovo TS130 ThinkServer about 5 or 6 years ago. Folks told me, RHEL/CentOS would not run on this server. I bought it and installed it and it works fine. So, a couple weeks ago, I decided to upgrade the memory. At the time, the bios only supported 16GB but it would be upgradable to 32GB. So, I started adding memory and figured I needed to upgrade the bios so I could get to 32GB. I got through 2 updates with rufus 2.11 and FreeDOS. Both installed with no problems. On the third upgrade, my USB flash drive is no longer recognized as a boot device. The fourth bios upgrade is a shell script run from RHEL which the support was also added later. I tried that first but it didn't work. Didn't get any errors, it just didn't work. Lenovo says use rufus 2.2 which supports MS-DOS. I can't get that version to create a bootable USB drive. It fails. I have tried .iso images and adding the bios files to it for a bootable DVD/CD. It boots but can't find the bios files. A dir of the DVD shows the flash.bat. I've tried plopt and a couple others. I'm stuck!! Any help would be greatly appreciated.

As well as everything on pendrivelinux.
