Popyacap Posted July 6, 2022 Share Posted July 6, 2022 First of all I am new here and find the menus difficult to navigate to what I am after. Never have been one much for the layout of forums. Sorry to the site for posting in the wrong place if I have done so. The longer I am at this the worse forums seem to get for any ease of posting. Things are too complicated. Been at this a long time and have followed many guides, all of which have failed. Simply put, I have a nvme drive and I want to place it into an adapter and boot from it. It will probably be a Linux or windows OS. The system I wish to boot the nvme: Intel q9550 CPU/Gigabyte EP45 Ud3P motherboard. BIOS (NON UEFI) To make this real simple I am trying to accomplish just one thing: put Clover onto a USB drive and have it bootable by this system. A more modern UEFI system has no issues at all booting the same drive. The old system in question was installed OS using a USB drive. The old system has BIOS only. No UEFI. So far all I have gotten is either a black screen with a non-flashing prompt, or endlessly "verifying dmi pool". If anyone can explain in steps (not missing any) this would make me very happy. At this time all I want to do is have "Clover" show up when I boot the USB drive. As, if I can't even get it to boot, nothing else matters.

Slice Posted July 6, 2022 Share Posted July 6, 2022 If you have a macOS somewhere then you can run there Clover.pkg to install boot sectors to the USB drive. Else do this manually in Linux or Windows. See WiKi. Or you can use one of available tool to create good USB drive image. For example Bootdisk Utility which works under Windows.

Yes, you booted not NVME, you boot another sata or usb. 1 Quote Link to comment Share on other sites More sharing options...
ricola Posted July 7, 2022 Share Posted July 7, 2022 Yes, I booted the bootloader (OC or Clover) from sata or usb, from the boot picker I choose to boot macOS (NVMe drive) Quote Link to comment Share on other sites More sharing options...
PippoX0 Posted August 21, 2022 Share Posted August 21, 2022 Hi,I used this method too . I have an usb with clover and NVme driver to boot my nvme SSD internal drive.Bios doesn’t “see” nvme SSD /pcie adapter , but Clover yes.PCI adapter is slower that native nvme slotI got 800mbs /Rw than 3500mbs/RW speedCheers Quote Link to comment Share on other sites More sharing options...
