I've been using XPEnology for about 3 years. I currently have JUN's bootloader 1.03b and a 6.x system that has been up for quite some time. I was looking to upgrade it to the new 7.x version. I've created 4 different bootable USBs - all different sizes, makes, and models. I've tried both legacy and UEFI images. UEFI image doesn't work at all for me. When I use the legacy image, it will boot to a GRUB prompt with a flashing cursor. Nothing else happens. They keyboard doesn't respond to any inputs at all (not even ctrl+alt+del). I let it sit for almost 2 hours waiting to see if anything happened, and nothing ever did. I've tried it with my test drive plugged and unplugged. I've tried the onboard Realtek NIC enabled, disabled, and unplugged. I always keep it disabled as I have an Intel dual 1GB NIC that I use instead in a bond. I've tried the dual NIC removed, installed and network cabled plugged in, installed and network cables unplugged, with the onboard NIC enabled and disabled. I've dropped down to a 0.9.2 version of the loader for the sake of trying a different one, and it does the same thing. I run all Unifi equipment on my network and it isn't registering as connected anywhere, so I'm unable to SSH into it either. Everything works fine in the "old" JUN loader. Any ideas on how to get this thing to boot to the GUI instead of GRUB? By the way, it isn't the command line grub prompt, it is just the word "GRUB" in all caps with a flashing cursor to the right of it.
*EDIT*
My setup is as follows:
AMD Athlon XP2
16GB RAM
Gigabyte GA-MA785GM-US2H
5 3TB Seagate Iron Wolf drives in a RAID 5 array with a hot spare
Intel Dual 1GB NIC PCIe card
For testing purposes, the RAID array is disconnected and I'm using a single 512GB SSD as my storage drive.
Thanks in advance!
