macOS Mojave from the App Store and, upon running it, it told me that my MBP (15-inch, Mid 2010, currently High Sierra) can’t be upgraded to Mojave.
Then it restarted my Mac… into the same installer again. This time, the installer complained of some missing files.
I booted back into my Mac and deleted the
.app file, but the boot menu (by pressing
Option during boot) are still showing 3 partitions:
mac OS Installer,
Recovery HD—in that order.
The weird thing is, both
mac OS Installer and
Recovery HD seem to open the same thing—a menu(?) where you can reinstall Lion(!!!).
My question: How do I remove
mac OS Installer from the boot menu? Or, at least, reorder the menu so that
OSX comes first.
I read on the internet to rerun the installer and cancel it there—well, I’ve deleted the file so I have to download it again, but now App Store prevents me from downloading it (“This version of macOS 10.14.5 cannot be installed on this computer.”—I know! Why didn’t you say so last time!)
My ubuntu is 18.04, and if I boot my computer with the press of the Tab and it will boot normally. But if without press the Tab, my computer will always be a black screen. I can’t figure out what problem is it. Can someone help me? If you need some more other information, Please let me know?
Using 18.04LTS, and last month when it updated and needed to reboot to ‘finish’, it locked-up upon reboot and has been doing this ever since – I go to boot up, it gets to the blank screen where the mouse pointer shows up, and then the pointer freezes, the light for HD access goes out, and nothing is responsive – dead…. So, hold down the power button, reboot, and it goes to the purple page with the count down and list, defaults, and boots up fine… thankfully there’s my VISTA64 laptop that works without all this linux grief, that I now have to depend on for daily work – and which btw works flawlessly (but no ‘updates’ to it to mess it up – too old for microslop) ~ sure wish linux did as well. Think I’ll have to wipe drive and restore backup image to fix unless someone knows what is bugging this thing… maybe then just cut off updates all together as they just seem to cause problems so who needs them ~ so much for LTS?
I want to encrypt my laptop. The problem is Screenshot 1
I have SSD 250GB with windows 10 is installed.
HDD 1TB which is empty
I have two physical drives, an SSD drive where Windows 10×64 is installed listed as “C” drive (Disk 0), and a 2nd internal HDD, listed as “D” drive (Disk 1).
When I go to Disk Management in Control Panel/Administrative Tools/Computer Management I find what seems to be the culprit preventing VeraCrypt from continuing encryption. The C drive is listed as “Boot” drive but not “System” drive, instead drive D is listed as “System”. Disk 1 is 500MB (System, Active, Primary, Partition) + 931GB Primari Partrition)
My goal is encrypt WHOLE disk C. And I want to set up password when Laptop is booting. And after encrypt disk D.
Im talking about second button encrypt the whole drive screenshot 2
How to do it? Help me please
Sorry about the lackluster formatting here. I’m typing this on my phone and don’t have a lot of time. (I’ll clean it up later)
Basically everything was fine until I woke up this morning and the system wouldn’t boot.
This USUALLY happens:
But sometimes it boots immediatly and then freezes when it gets to the OS after about a minute or two.
The highest CPU usage items are btrfs-transacti and a random kworker.
The strangest thing is that I can’t boot from a live USB. I have no idea why. It just loads the Kubuntu screen forever.
I have btrfs snapshots of the system and home, but I cant access them because I cant get to the live usb.
There was a message about “a usb cable being bad” in the boot menu, but I dont know if that helps.
I have a mempry test running right now, but I’m on my way to school, so I can’t tell you what the results are yet.
I booted the OS in recovery mode and ran fsck and dpkg repair. Also, booting the previous kernel did’t seem to help things.
Is there any way to restore the @ or @home subvolumes from the OS itself without using the live usb?
How can I restore the system to proper operation?
I tried to mount my external hard drive through the terminal. First I tried sudo mount /dev/sda2 /mnt, but nothing happened. Then sudo chown -R username@username mountpoint. I kept getting invalid user name. Last, I tried sudo chown -R (username) /dev/(devicename). Where device name is I put what I thought was the name for the seagate hard drive. It was under Linux File System. I restarted my laptop thinking maybe something I had already done worked. Now at start up it goes to boot manager. I can either choose Ubuntu or Advanced options for Ubuntu. If I pick the first one it goes to a black screen with /dev/sda2: clean. Then it goes to another black screen and ask for my username and password. When I type that in the screen is still black with information about Ubuntu. I think I need to put a command in but I have no clue what I did to get it to this point. In the Recovery Menu there are a lot things I could do. I don’t know what I’ve done or if I can even fix it without losing everything on my computer. Now that I’m looking a bit closer it says that the Filesystem state is read-only.
Same question asked here and followed David Anderson’s solution, but running into issue on reboot: Dual-Booting OS X or macOS with Linux without rEFInd
If I reboot without holding Option key and then selecting Debian, I get stuck at Loading Initial Ramdisk. It only boots properly if I hold Option key. Soft or Hard reboot doesn’t matter.
I’ve tried some Grub options but I can’t find any that resolve the issue.
I’m having a weird problem when I try to install Ubuntu on my laptop. I have created a bootable USB drive, with the iso imagen of Ubuntu 18.04, and I also accessed the BIOS and changed the boot order so that the laptop will boot from the USB. After restarting the computer, it does indeed open Grub with the usual options (try Ubuntu, install Ubuntu…), but when I select “install Ubuntu”, the screen turns black and that is the end of it. No matter what key I press or what I try, nothing works, and I need to switch the computer off by pressing the power button.
I am at a loss. What can be the issue here?
Just installed 18.04 on a Lenovo Carbon X1. It worked fine for a few days, but now when I boot and select Ubuntu 18.04 on the GRUB selection screen, the screen goes purple, then black. There’s no Ubuntu (….) splash screen, but the desktop shows up for a split second before going to a black screen with a mouse pointer that I can move around.
When I go into recovery mode -> resume, everything seems to work fine but the resolution is different (onscreen text is smaller).
I can get into tty2 but running startx doesn’t work.
I disabled Wayland via this. No change. Then I tried Step 1-2 of this. No change.

this is an HP7265NGW. I’ve removed an M2 disk and put an old SATA1/WD-500Gb (debian 9 64bits) that was previously working fine on this machine.
Now, the SATA1 can’t boot (either UEFI or Legacy), the BIOS error is the HP classical
Boot Device Not Found Please install an operating system on your hard disk. Hard Disk (3F0) F2 System Diagnostics For more information, please visit : www.hp.com/go/techcenter/startup
The SATA1 disk boots perfectly on other machines.
- ALL the HP Bios diagnostics state that the disk is in perfect state.
- Debian Rescue is capable of mounting the filesystem, no errors, and making a grub reinstall, no errors. But after restarting, 3f0!
- BIOS was updated to today’s last version. No effect.
- Tried Legacy/UEFI. No effect. UEFI boots a black screen, sometimes.
Minutes ago, I’ve just discovered the HP BIOS option “Boot From File”, where the disk is identified, some “EFI” directory, and some “.efi” file… boots fine!
How can I fix this, or at least make “Boot From File” my default? pressing F9 and searching for the EFI file every day will be annoying!
