Hello, please bear with me, I have bad eyesight (disabled) and had 12 strokes, also leading to disability in the form of aphasia. It means I can't understand as I used to.
Okay, so I started my IT career on a Sanyo MBC-1150 running on CP/M-80 with 4 or 8 k RAM and a 64K ROM. That was roughly forty years ago. I have been using LinuxMint Cinnamon for the past decade or so, after having tried from AriOS to Zorin. Mint Cinnamon always just worked BUT, there is a deficiency. It doesn't really do KDE apps well, as I need KDE Connect for my Samsung Galaxy S7, for interactivity. I want to transfer photos, contacts, etc., to the laptop via bluetooth.
In Windows 10 Pro build 1909 and always updated, the Bluetooth doesn't really work with the Samsung's Android 8.0 Oreo, also always up to date. Don't even mention updating, I am diligent yet it doesn't help.
So I fled to Manjaro after having had a bad Kubuntu experience in that Kubuntu apps didn't always work. I downloaded the Manjaro KDE ISO last night, made a bootable Sandisk USB -flash drive and booted the hardware, a Lenovo Thinkpad Edge E540 with Intel 1i7 4702MQ 2,2GHz CPU, 8GB DDR3, 256GB Samsung SSD. Pretty fast for Linix as I only browse, do office work, back up to external RCT 1TB HDD USB3.0 and otherwise email. That's it.
So, today, I installed Manmjaro KDE, it ran well and I updated the software first, then set up the Plasma and stuff, then rebooted. Up came GRUB and a dead laptop. On a brand new installation.
I spent all afternoon to install my Windows 10 Pro as I have urgent volunteer work to do.
Why would GRUB come up blank on reboot? It booted well the first time.
What do I do when the screen just shows a grub and some dialogue and nothing else? I did it ages ago but the brain damage after the many strokes really doesn't aid me. Can anyone please help as I want to dual-boot at least.
