Description of problem: Trying to reinstall Fedora 22. The initial install worked fine. Running the installer now gives me a blank screen with a flashing cursor in the top left corner. I tried running the F22 Live CD, and I got an error "uncompression error, --system halted". I found some threads that suggested it was a memory error, so I tried running Memtest from the GRUB menu, and the laptop immediately restarted. The netinstall USB is the same one I used to do the original install, so I know it is OK. The Live CD USB works fine on my T520, which also has an encrypted disk (if that is relevant). Version-Release number of selected component (if applicable): Fedora 22 How reproducible: 100% Steps to Reproduce: 1. boot from USB 2. 3. Actual results: Expected results: Additional info:
I would suggest looking more into ways to perform the memory test. Everything you're saying indicates that your computer is not booting, which means that either the media you are using to boot has gone bad, or something in your computer has.
David, I can still boot to the installed F22 system. I just can't reinstall Fedora. There are actually three problems: 1. reinstall does not work 2. Live CD does not work 3. Memtest does not work. Note that a Ubuntu 15.04 USB boots fine on the same system. I can also run the extended memory tests from the Lenovo diagnostics menu (F10), so it is not a hardware problem. Don
- I also tried RHEL 7.1, it showed a similar blank screen with a cursor at the top left, then rebooted after a couple of seconds - I tried the netinstall image with some of the kernel parameters in 'Common Kernel Problems - Crashes/Hangs' (https://fedoraproject.org/wiki/Common_kernel_problems?rd=KernelCommonProblems#Crashes.2FHangs) removed quiet added vga=1 initcall_debug acpi=off nolapic noapic noapictimer earlyprintk=vga nosoftlockup edd=off It still showed just a blank screen with a cursor - I also tried the boot.text boot option, same result
I created a Fedora 22 VM on my current T520 laptop using the same netinstall ISO. I used the same options (auto partitioning, full encryption). I was then able to boot from the ISO after installing Fedora, so it seems to be a problem only with the W541. Odd that the initial installation had no issues. Can you suggest any diagnostics, tests, workarounds?
I recreated the USB using the disk utility in Fedora 22, and it worked. Somehow writing the same ISO with dd on RHEL 6 did not.
