PaulieM - Thanks again, and Happy New Year! This is great info!
1) Dumb Q - on my Optiplex 7010 MT, after setting up your BIOS mod or Clover, I plan to clone my existing HDD onto an NVMe M.2 that will be plugged into my PCIe x4 slot (or maybe even my PCIe x16 slot). a) Therefore, I think I should be skipping your "Create your bootable Windows Server Installation" and "Install Windows in the normal way" steps. Please confirm. As I said, dumb Q, but best to confirm.
b) However, when I follow your steps in "Setup the Clover EFI USB Boot Stick", must the NVMe M.2 SSD first be plugged into the PCIe slot so the Boot Disk Utility "sees" it while creating the Clover USB stick? Note that I would not have cloned yet, so the NVMe M.2 SSD would still be blank, and I would still be running everything off my existing HDD.
2) Unlike your careful articles, the "http://cvad-mac.narod.ru/index/bootdiskutility_exe/0-5" page has no step-by-step detail. Your steps are clear, but if something comes up, is there a site that explains the options in the cvad-mac.narod.ru Boot Disk Utility?
3) As you are very knowledgeable, to put it mildly, your link to the cvad-mac.narod.ru site gives me a bit of confidence that its Boot Disk Utility for Clover is OK. Normally, I don't run apps from a Russian source. (I stopped trying stuff from Giveaway of the Day a long time ago, unless it's an update of something from, say, a reputable company like Ashampoo.)
So, do we know whether anyone has checked the coding in the Boot Disk Utility to confirm it's clean?
4) My existing HDD for OS dual-boots my PC, bothWin 10 Pro 64-bit (currently v 21H2, and which I now use almost al the time) and
Win 7 Pro 64-bit (which I hardly use any more but which I keep updated using the method at AskWoody).
Also, my PC has two other HDDs that I use for data, that I will NOT be cloning to NVMEs.
If I clone my principal HDD (with my OSes) to an NVMe M.2 SSD, do you think that Clover or your BIOS mod will still let me dual-boot off it?
(I will probably use Macrium Reflect to clone, unless you recommend a different program. Also, now, my PC runs iReboot from NeoSmart Technologies to let me elect which OS to reboot to. It would be nice if everything continues to work the same way after I've cloned my OS HDD to the NVNe M.2.)
5) It turns out that my new SanDisk tiny 64GB USB stick is "Cruzer Fit USB 2.0". Should I swap it for your suggested USB 3.0? Will it make a difference if this is where I have the Clover first boot? It will eventually be sitting in the USB slot INSIDE my Optiplex 7010, and I don;t know whether that USB slot even has the 3.0 speed.
Many thanks !!!!
