UEFI and FOG
-
Thank you very much in advance.
I have a HP prodesk 400 SFF computer and installed Windows 7 64 bit on that machine. I disabled the UEFI to boot through legacy and installed Windows that way. When I go to upload the image afterwards, I get an error message saying “error trying to save gpt partition tables”
My dell’s are working just fine uploading and downloading images, just for some reason these HPs are giving me a hard time. Would anyone be aware of this issue?
-
These HPs came pre installed with Windows 8 and we are downgrading them to Windows 7 for the district. Wanted to try to give you all the necessary information. If I keep UEFI enabled I have to manually boot to the FOG server because it will not boot to the PXE server, only in legacy mode will that work. If I was install Windows 7 with UEFI enabled, the image uploads and downloads just fine but like I said I have to load to the PXE server manually as UEFI won’t boot to the NIC card.
-
It sounds more like a firmware or manufacturer partition issue rather than a UEFI issue. When you downgraded to 7, did you wipe the drives?

You have to specify a different boot file for UEFI. There are two good threads on the topic and one WiKi artle that is under construction but viewable.

@need2 When I downgraded to Windows 7 I deleted all partitions and then installed Windows 7. It seems when I upload the image as a RAW file it worked, now I am going to test out the others again because that became a 50 GB image which is too big.
-
even when you remove the partitions and reinstall windows, it doesn’t always clean up the first few sectors of the drive and fog can see remnants of GPT partition structure. try running fixparts to clean up the partition data before uploading.

@Junkhacker OK so you’re thinking that things should work perfectly without using RAW to upload the file if I run that fixparts program to completely wipe the sectors? I’ll give that a try! Thank you
-
@Junkhacker I have never used fixparts and when I try to type in the disk number it exits the program

@Uncle-Frank Awesome thank you. I finally decided to use linux and run fixparts and now it uploads perfectly. Thank you very much for your help!
