[NAME]​ I see some hick up from Win 11 on certain machine but not Win 10.  Without a specific clue, it's hard to guess the reason.  A Win 10 USB created by creation tool is universal self-created and is hard to make a mistake with.Tested with older boards and it's working too.  Intel, HP, Dell, they all got to selection of partition for installation.  CPU tested with Core 2 Duo E6600, Core 2 Duo E7200, Athlon II x4, Athlon II x3.  Only a Dimension 8400 I had struggle with and settled for a 32-bit installation instead.  It has a Prescott Pentium 4 I think.Testing prep for the Inspiron 530, set BIOS (1.0.18) to RAID, and first boot to hard drive (as USB is considered hard drive group).  Tapping F12 away and Win 10 USB drive appears in boot group for selection.  May take up to 10 seconds for that blinking dash to turn into Windows logo (boot).  It also works well with Win 11 created by Rufus tool to strip all hardware requirements. Take it a validation or encouragement.  That's all I can say.
tried many times, it would not work Win 10 and Win 11 run fine on the studio 540S. trouble with 530 is that it is like some aurora model with a fixed IO shield built in case.  I can not even put a 540S motherboard in 530 case unless i drill some custom hole to modify the oem IO shield.  quite dumb for Dell to do that. still do not understand why it would block win 10.  not that I have to because it runs 7 well and can be used as a retro pc.  I just want to understand the root cause of the OS block. user benchmark shows some users do run 10 on 530.  not sure if they have a different ver of oem motherboard or bios needs to be updated.  I thought my 530 bios is most recent but i will check again.
Can not install or run Win 10 on old Inspiron 530 MT
