Sandi, Answer to your last question first, I am a pensioner, I write slow, make mistakes, (hence 20.18 should read 18.04), I need a good spell checker, so I use writer to prepare what I want to say then I paste it into the email, I must remember to paste as raw text in future.
The computer that I am having problems with is as follows :- HP ENVY 15-AH151s 15.6" Laptop - AMD A10-8700P - 8GB Ram - 1TB HDD - Bang & Olufsen Audio Win10 Sold second hand by Amazon/Luzern, It arrived Saturday, June 25 2016 The computer came with windows 10 installed. My plan was to remove windows 10 and install Ubuntu 16.04. I had previously converted three desktop and two laptop PCs to Ubuntu without any problems, the latter being a Lenovo G50-70 Laptop converted from window 8 and is now running Ubuntu 18.04 I set the HP Notebook to Legacy Bios and disabled fast boot. Startup Disk Creator was used to make a boot USB, with witch I used the “try Ubuntu” option to ensure Ubuntu would run on this machine, all seemed OK so I started the install procedure. I chose to use the whole hard disk for Ubuntu as I don’t use Microsoft. The install went fine, all complete I was instructed to re boot, a black screen was the result. I rebooted into setup mode and selected the ubuntu option and got a screen full of cascading code. I booted with the USB in the “try Ubuntu” mode, all the Ubuntu file had been installed but the uefi would not let them load I took the computer to a computer repair shop, the man said it will be ready in 24 hours. Five weeks later he gave me the PC back and said it was something microsoft or HP had done wrong! Over the months that followed I saw many different screens, Ubuntu logo, static code, blank screen etc! I list things I have tried in many combinations (Note, I can copy and paste code but compiling code is beyond me). Gparted, Boot repair, Disks, re formatted the hard drive in both MBR and GPT, Legacy Bios and Secure Boot. When I click on “disks” I see the following three devices, 1.0 TB Hard Disk WDC WD10JPVX-60JC3TO 1.0 GB Drive Generic Flash Disk, (this is my USB boot drive) 1.5 GB Loop Device /cdrom/casper/filesystem.squashfs I think the Loop Device is the cause of the problem. I’ve tried to delete the Loop Device and or the rofs directory but they won’t let me. I was hoping this would allow me to run Ubuntu in legacy BIOS mode. After about a year of trying all sorts to get the computer to work I sort of gave up. When the CPU manufactures where found out to have been making faulty processors the computer manufactures started modifying firmware and software to get round the problem. I got my sick laptop out of the cupboard to see if it would work, after many weeks of trying different ways of installing and trying to boot Ubuntu it suddenly booted up, but it was several more weeks before I got it to boot up again. I never seems to boot up the same way twice, When I managed to get the machine going occasionally with 17.10 in efi but never in legacy bios mode. When I first tried to install 18.04 by usb it would not load but it did the last time ai tried. The ratio booting up can be anything between first time and giving up after 50 attempts UKUU (Ubuntu Kernel Update Utility) ?
