I am dual booting a computer to build android but it is a family computer and my mother wants it so that it boots straight to Ubuntu so she doesn't have to choose Ubuntu or windows. Is there a way to set it where it boots straight to windows and if I want to boot into Ubuntu I mash a button that takes me to a menu? If so help would be appreciated. Thanks everyone!

In Ubuntu 12.04 (or above), how do I set the GRUB time and the default OS (that I see at boot time) as I'm dual-booting Windows (7/8) and Ubuntu (12.04 or above)?

I'd like to have Ubuntu installed on a USB stick, that I could plug in (almost) any computer and boot from it, and that I could use (almost) normally, as if it was installed on that computer. I'd also like to have a data partition on it that could be used by (almost) any computer, mostly to store some portable apps, just in case.    I've been told that if I installed Ubuntu in BIOS mode, I wouldn't be able to boot from a computer in UEFI mode, and vice versa.  Since I'd like to be able to boot on any computer, it's a big problem.  What can I do to be able to boot on computers in BIOS or UEFI modes in my case?  I've been searching for solutions but most of them are for specific needs that are different than mine, so it's difficult to extract the minimum requirements from those solutions to apply them to my problem.  Is there a simple, "clean" and quite generic solution to this problem?  I'd appreciate some explainations about the reasons why a specific solution is good or a specific step is needed.    My current setup:   USB stick:  OS: Xubuntu 16.04 i386 installation: full install (from a Live USB built with Rufus) drivers: none proprietary file systems:    partition table:    2: , /boot/efi, 128 Mio, FAT32, [boot,esp] 3: , 128 Mio, HFS+ 4: , 2 Mio, [bios_grub] 5: swap, 512 Mio 6: , /, 24 Gio, ext4, defaults,errors=remount-ro,lazytime,commit=60 1: , /media/data, ~3.6 Gio, FAT32, defaults,lazytime,check=strict  RAM:   /tmp, tmpfs, defaults,nosuid,nodev,noexec,mode=1777   swap:    vm.swappiness=5 swap partition: 512 Mio, for emergency zRAM swap files:    /var/swap/hib.swp: same size as RAM, for hibernation, generated by a script at startup /var/swap/opt.swp: if needed, generated by a script   overprovisioning: ~5.6%   built-in: ~1.2 Gio (apparently) added: 512 Mio  scheduler: deadline

I'm discovering the possibilities offered by persistent live USB using Ubuntu 19.10 and I was wondering if it would be possible to boot with Ubuntu on Android (i.e. using your computer capabilities through your smartphone) using those multi-plug USB sticks which have both USB3 and micro-USB2.  In other way: can I get some kind of a boot menu on an Android device in order to boot with a persistent live USB in order to access my Linux computer tools and setup from a wider range of devices?

I have a windows 7 Computer.  I want to install ubuntu.  I know if I install to the unallocated it will set up the multiboot like it should.  However, I want to set the partitions up manually, I want different stuff in different partitions, e.g. logs.  If I do this, will the installer still set up the multiboot like it should?

I have a solid experience of installing different OS (Linux, Windows,...) on PC. I would like to try just for fun to install Linux on a unbranded Android low cost tablet acquired in 2015. I spent some time browsing the web and as far as I understood there is a risk that during the flash procedure the device could be potentially damaged. So I read extensively on how to backup the ROM using TWRP and all related matters. I would like just to have some explanations on the below topic:    Scenario #1: I have a PC, if I want to try another OS I can just format the hard disk and install it, in no way there is the risk of damaging the BIOS motherboard. Motherboard and hard-disk are separated, so no problems may arise.  Scenario #2: I have a tablet, want to wipe out Android and install an upgraded version of Android or a Linux distro suitable for mobile devices.     Why in this scenario there is a risk to get an unusable device?   Is this because in this case motherboard and unit memory are bundled together? So wiping the memory will also erase the configuration settings of the motherboard?   Do we have here the equivalent of BIOS settings?

I need to install Ubuntu instead of Windows 7. Can you tell me the steps to do it? I don't want to install Ubuntu alongside Windows. Any precautions needed before installing Ubuntu? How do I install Ubuntu 11.10 without losing the current data in my laptop?

I'm not sure I'd actually do this, but is there a way to make GRUB automatically select the boot option I didn't use last boot? i. e. If I booted into Windows last boot, it selects Ubuntu. If I booted into Ubuntu, it selects Windows. I was just wondering because I often find myself rebooting to switch OSes, as I have different games that I run on each (though with my new rig I don't need to run stuff on Ubuntu just for lower OS resource usage), and I was wondering if I could make it so that every time I pressed "restart" from either OS I wouldn't have to change selections. In practice this would also affect non-restart startups, so then I might have to boot twice to get the OS I was using last time.

Why is everybody keep mentioning to disable Fast Boot on Windows 8 if you have installed alongside Ubuntu? Is it something that is recommended only for UEFI machines or is it a suggestion for Legacy BIOS machines as well? Is it because it makes the Windows partition inaccessible from Linux or there is another more serious reason to disable it?

I installed a mainline kernel for testing purposes. I would like to set grub to boot from the older kernel by default.  I know I can set the GRUB_DEFAULT=0 setting for the first page of grub but how do I set it to boot by default from one kernel in the second page (Advanced page)?  I would prefer doing this without installing other software (ex. grub-customizer).     Related Questions:

My system is not dual-boot, I run a standard Ubuntu desktop system "on the metal" (I think running it in a VM is the same).  Pressing c while booting does not cause the GRUB menu to appear (which I believe it does for a dual-boot system).  How can I get the GRUB-menu to present itself on a single-boot system?

I just installed Ubuntu alongside Windows 7. Now I cant boot Windows 7 because it automaticaly boots Ubuntu without displaying boot menu. How can I get menu with options to choose which Os to boot? Can anyone help?

Whenever I boot on Ubuntu, I see the entire GRUB menu by default. Is there a way I could make it simply auto-boot if uninterrupted within X seconds? I remember that this was the case on previous releases of Ubuntu, it would only show the GRUB menu if you held down a button during the boot.   How can I make GRUB do this by default and just get on with the boot process?

I recently have upgraded my PC, my new Motherboard (ASUS M5A99X EVO) uses UEFi instead of the regular MBR option.  I have a Ubuntu 11.10 installation that I did when I had my previous hardware (MSI MS 7267) , Ubuntu alone boots fine, and so does Windows 7, however Windows 7 is using UEFI (GPT) boot whereas Ubuntu is using MBR.  I have my OSs in separate drives, so that GRUB2 wont' get replaced by the Windows Bootloader and viceversa, as I said both OSs boot fine on their own, but to do that I have to disconnect one drive in this case the Ubuntu drive as it prevents Windows from loading.  Now my question is, How can I change/convert Ubuntu's drive so that instead of using MBR it uses GPT and allow Windows to boot?.   Preferably without reinstalling the whole system or lose any data.  And if I were to wipe the drive, How can I install Ubuntu in GPT, UEFI, whatever it is mode?.  I have used gdisk to convert from MBR to GPT, but now Ubuntu can't boot seems like grub just doesn't start.  I have re installed the OS, and the drive is GPT now by default however grup-pc is still being used instead of grub-efi.  How can i make Ubuntu boot from EFI?.

I stopped dual booting and I don't want to have to choose the OS any more. I want to boot into Ubuntu 12.04 directly without seeing the GRUB menu.  How can I achieve that?

My computer shipped with Windows 8 and later I upgraded to Windows 8.1 Right now I'm trying to get Windows 8.1 to dual boot with Ubuntu 12.04, but the Grub menu doesn't show up at all. My computer just boots straight to Windows. I searched for this online and the only answer I get is  to edit /etc/default/grub, but I don't even know what this is and where to find this. I also can't use a bootable CD, only a USB. I really need step-by-step answers that aren't confusing like all the other ones I've found so far.  EDIT: I just rebooted and now the Grub menu does show up but when I try to boot into Ubuntu, it says a file is missing. Windows boots normally though. I have disabled secure boot and fast startup.      Windows failed to start. A recent hardware change or software change might be the cause.     To fix the problem:     1. Insert your Windows installation disc and restart your computer.     2. Choose your language settings, and then click "Next."     3. Click "Repair your computer"     If you do not have this disc, contact your computer administrator or computer manufacturer for assistance.     File: \NST\AutoNeoGrub0.mbr     Status: 0xc000007b     Info: The application or operating system couldn't be loaded because a required file is missing or contains errors.   I'm not sure if that file was corrupted while installing Ubuntu or it's missing.
