I have a problem on Oracle VirtualBox : it regularly tells me that I don't have enough space left on device, when updating or installing.
In the VB settings, I have set my Motherboard base memory at 3370MB.
My HD IDE Primary Master has an actual size of 2MB and virtual size of 20GB, and my Optical Drive IDE Secondary Master is 1,46GB.
The Linux distribution is 1.534G.
When I run df -h in the VB, it tells me that the full filesystems are :
/dev/sr0, 1.5G, mounted on /cdrom
/dev/loop0, 1.5G, mounted on /rofs
/cow, 1.7G and 72k available, mounted on /
I am running it from a Windows 7, and the distribution I use inside the box is the latest Linux Mint.
I don't know if this is the relevant information you need, please ask me if you need anything else.
Thank you in advance for your help
Ok, I found the solution. The problem is that if you don't install Mint inside of the virtual machine, the only space available is your memory, so it is used as drive space. The solution was to first boot it via the live CD version, then install it inside of the virtual machine, and then reboot it using the version of Mint you just installed on the virtual hard disk you have in the virtual machine.

I'm using parallels an an m1 macbook pro and the virtualization of ubuntu 20.04 worked perfectly fine until today. I can't launch it and it tells me that "Image BSS overlaps adjacent EFI memory region".
Does someone know how to fix it ?
I also can't create a new virtual machine since it prints the same error when I try to launch the new one.
Booting into an older version of the Kernel allowed me to safely access the VM after this happened to me. Although I also was running out of disk and needed to increase the amount of disk space allocated to the virtual machine.
I believe the latest version of the Ubuntu 20.04 kernel may not work on Parallels for now. Specifically linux-image-5.13.0-35-generic gave me trouble and booting into linux-image-5.13.0-30-generic worked fine.
The steps I took were
Attempt to boot into VM. It should hang at Parallels error: "Image BSS overlaps adjacent EFI memory region"
Go to Actions > Stop
Attempt to boot into the VM once again, at this point it should allow you to select Advanced options for Ubuntu. Select this.
In this screen select an older kernel version to boot into. I didn't have to boot into Recovery Mode.
Uninstall the breaking kernel. I just did sudo apt-get purge linux-image-5.13.0-35-generic.
It should be noted that I had older kernel versions available. If you've also deleted older kernel version preemptively, then I'm not sure what can be done.

I installed Ubuntu-20.10 on my computer. So now there are two operating systems on my computer, Ubuntu and Windows 10. But I turned on the computer and found that the computer automatically entered the Windows operating system without entering the selection interface of operating system. And there is no Ubuntu startup item on the boot option in the BIOS.
My guess would be the installer didn't make a boot partition. Could be allot of reasons.
Does your bios have UEFI ? some bios will launch a usb installer not from UEFI with can screw up the installer. other times it's just a wrong button pressed.
usually people have the opposite problem. Make sure your bios is up to date and when installing again check the partition summer before you hit install to make sure its making a bootable partition or including it somewhere.

I am not familiar to grub, and very less to linux.
What i currently have is the recovered linux machine disk.
Which has grub bootable source machine, but for booting on other platform (hypervisor/cloud)
My team used an extlinux to make it bootable by overwriting its boot code and make that machine bootable on other platform like cloud/hypervisor.
Did something like in this link
I want to make that machine grub bootable so i tried and came up with something below:
Created 1 gb disk.
installed grub using command on fat32 partition using below link
Content of grub.cfg
menuentry 'usbboot ubuntu' {
set root (hd0,1)
linux (hd1,3)/boot/vmlinuz.efi root=/dev/sdb3
initrd (hd1,3)/boot/initrd.lz
}
After that i created vm. Attached 1GB disk first then recovered disk second.
please help me to resolve issue
I was able to solve the issue, Issue is their was no such device like /dev/sdb3,It may be due to hypervisor type. So i was trying mount command in BusyBox and i found it their as /dev/vdb3.

I have Linux both command line linux, and Ubuntu, but my computer is Windows 10 based. Also the hardware is not what it used to be. I.e... No working USB port, No DVD slot (But I do have a Micro SD slot if I can boot it from there) but I was wondering if I can install and boot linux directly in Windows? And I was wondering if Windows 10 would be active still, and if I an switch in between the two? I have never worked with Linux or booted it. How can I boot linux in windows without anything but a micro sd card?
you can not boot linux on windows. you can make Bootable USB and use live linux or use virtual machine like VMWare
Use a virtual machine. They allow you to run multiple operating systems at once, and as long as your machine supports virtualization, they work perfectly for the situation you are describing.
My preferred virtualization software include:
VMWare
and
VirtualBox
From there, download and install the Linux .iso file of your choice to be able to open and switch between operating systems at will. Also, make sure to enable virtualization in your BIOS settings.

I am dual booting on my Lenovo t420 windows and Ubuntu. I am using both Os and find it annoying to switch back and forth...I was wondering if I could have Ubuntu on my Virtual Box and copy my information from the Dual Boot to the windows partition. I have lots of stuff on my Linux, mainly because of eclipse and android stuff.
look at this link:
https://forums.virtualbox.org/viewtopic.php?f=2&t=9323
it is possible that this may not work because when an OS is installed, it loads only the files to make it run on your specific machine. the simulated hardware in virtualbox might be too different that what it uses now.(I know this because I tried this with win xp)
If you're running Windows 7, you can use 'Windows Virtual PC', which is built in to Windows 7, to run a Linux OS as virtual machine. See http://answers.oreilly.com/topic/366-how-to-run-linux-under-windows-7s-windows-virtual-pc/ for more info.
I'm T420 with both Ubuntu(12.04 64bit) and Win7 too. Normally I can see Win7 partition be mount to Ubuntu and I can copy data from Ubuntu to Win7.
