I am trying to install CentOS 7 and understand what is the best way to do this. I have the CentOs image on a micro SD card and tried to install it on a USB thumb drive, but on install, it is not seeing the USB drive as a destination. Also what is the preferred location to install for performance? Would it be better to install it from the USB drive to the micro SD drive or vice-versa?
Preferably do not install an OS on an USB thumb drive for permenant use. Install it on the build in eMMC, or on an external disk through M2 or Sata interface If you make an installation image for CENTOS it does not matter if it is on a USB Thumb Drive or a SD card. If you have an old Udoo X86 that has not got an UEFI update it is not possible to use an SD card.

Thank you. I noticed when I would go through the installation menu, I could never select the SD card for intallation. I even had a difficult time selecting the eMMC as I had to go to custom formatting to erase and allow installation there. I will see if I can update the UEFI to see if that makes a difference.
I was on BIOS 1.01. Getting some error messages with update which seemed to go fine [no errors with each step until the end]. Not sure what to do at this point.
Make sure all the prerequisite software packages/libraries are installed before running the script. CENTOS is not installing the same as other Linux dostros like Ubuntu. See the update manual (pdf) for the prerequisite software packages/libraries. Else make a Bootable Ubuntu LIVE or Freedos USB disk and update from that. Instructions for the DOS update are also in the update manual.
