Installed but no boot option SOLVED

Post by bernardsun » Mon Apr 14, 2014 11:07 am

Hello again folks, I must ask for more help.
With your helpI have installed Mint apparently successfully but when I switch on, Windows 7 boots immediately with no options offered.
If I hit the F8 button to get the boot menu, Mint is not there (picture on link at end)
(The P1 and P3 options both boot into Windows. In order to run from DVD I had to use this menu and the DVD drive appeared as the last item)

My BIOS is the UEFI system. I do not find it as straightforward as the old BIOS and am reluctant to mess with it.
Running Paragon Partition Manager in Windows, it appears that Mint is installed in Ext4 (picture on link at end)

I have been unable to find a previous answer to this particular problem, unless it is the following which was suggested elsewhere by Gold_finger:

Note: On some occations the installer does not reboot the computer properly when installation is complete and that sometimes results in an improper installation of the bootloader. (Doesn’t happen all the time and don’t know what causes that.) I’ve found that the best thing to do when installer completes is choose «Continue testing» instead of «Reboot». Then wait for about 15 seconds after the installer’s window closes and shutdown the machine normally: Menu -> Logout -> Shutdown (or similar depending on which version of Mint you have).

Could this be the answer? In order to apply it I would have to install again. Would a new installation overwrite the existing one or would I have to reformat or something?

I have uploaded pictures to a page on my own web site:

You may have accidentally installed Mint to your UEFI system in MBR mode instead of UEFI mode (yes, that is very easy to do)
There is a way to correct that, but first, if that is not the case, and you are installed in UEFI mode, then this boot manager program might help —

Well,Thanks Austin but it looks like this is getting beyond me. I looked at the rEFind pages and if I had a week to spare I might get to understand some of it. I would not risk trying to install this boot installer to replace my current system without much fuller understanding.
I have followed its advice to check my disc and the result is added to the page of pictures —

This mentions MBR whereas my ‘BIOS’ screen says UEFI. So I am baffled. To be honest, I would rather remain baffled. I have my own level of expertise and I don’t have time to add this to it so if there is an easier way, I would love to know it. Otherwise it’s goodbye Mint.

If installation could have been incorrect, how can I reinstall and know that it is correct?

It’s very possible that happened to you. Since your installation is to MBR partitions, don’t worry too much about messing with UEFI settings. Also that boot menu you get by hitting F8 is not going to show Mint — that’s only meant for directing which device/drive to boot from. The drive itself contains the actual bootloader for the operating system, but Mint’s must not have installed correctly. (I don’t know why.)

Best bet is to boot again using your live Mint installation disk, then follow the instructions here to install the Boot-Repair utility and run it: https://help.ubuntu.com/community/Boot-Repair. Follow instructions for «2nd option: . «. Just copy/paste the commands shown rather than trying to type them out. Run the «Recommended repair» and copy down the url link that it gives you at the end just in case we need it later. If that doesn’t solve problem, post back here with the link.

Please add [SOLVED] to your thread if a solution is found. Go to your first post in the thread, hit «Edit» button and add [SOLVED] to the title of the post.

No option to boot into ubuntu after windows update

I had Ubuntu and Windows 10 dual boot. I recently got an update for Windows. I did it. Before update, GRUB menu used to appear. But now, Windows boots directly. I tried very much but it seems no option to boot into Ubuntu. No boot option in BIOS. I can still see Ubuntu disk in diskmgmt.msc in Windows. I am using Ubuntu 20.04 LTS with Windows 10 Dual Boot.

Keep reviewing your BIOS boot priority options as sometimes Windows updates will reassert themselves as the primary boot priority. Also ensure that «fast startup» is disabled in Windows. If these do not work, search for how to use boot-repair from a live session. After doing all three of these tasks, if you still have a problem, please edit your question and include the details of exactly what you did and the detailed results of each attempt as well as the boot repair summary output.

I advise against EVER using boot-repair. Grub has gone away, possibly due to Windoze updating BIOS but either way you should just need to re-install grub. It’s a good idea to save your grub in text format in case you have special edits because you never know when you may need to re-install grub when you are on a dual-boot system.

Boot-Repair’s main fix is just a re-install of grub or update of grub menu. But its report can really help others in suggesting the best fix. But both Windows updates & grub updates will reset UEFI boot order to have its system first. You may just need to go into UEFI settings (not UEFI boot menu) and change to have ubuntu as first. But Windows udpates also update UEFI settings & you may need to redo some of those.If old BIOS system, Windows may have updated partition table leaving off Ubuntu partition which can be fixed, but need Boot-Repair report to see details.

I Installed Ubuntu many times, but it’s not working, there is no option to boot Ubuntu

I installed Ubuntu in a Windows 7 PC in its G: partition. But after installation and restarting the PC, there is no option for boot to Ubuntu. I am not a computer expert. Please help me. During installation how do commands work.

I suggest you to enter the askubuntu general chat room in order to receive real time advice from connected users, click here: chat.stackexchange.com/rooms/201

Install it on your main drive, usually /dev/sda.

It should automatically see your Windows partition, and you’ll be rocking a dualboot.

Another option is to restore the Windows Bootloader after installing Ubuntu, and then proceeding to use EasyBCD to add a boot loader entry for Ubuntu.

I triple-boot OS X, Windows, and Ubuntu with the Chameleon Bootloader.

It automatically recognizes all my operating systems (all on separate drives within the same computer)! Plus it has a GUI. I love it!

If you installed Ubuntu using a USB, try booting the computer with the USB connected.
If you see Grub and Ubuntu boots then follow the solution in this question.

EDIT : Extra info as requested

Hold «ctrl & Alt» then press «T» and that will open a terminal.
Grub is the bootloader, basically a screen which will allow you to select booting Windows or Ubuntu (using the up / down arrows and pressing enter).

As suggested above try booting with the installation USB connected and let me know what happens.

sdx will probably be sda assuming you are installing to an internal hard drive and only have 1 internal drive. Linux uses sda, sdb, sdc to identify drives and sda1, sda2, etc to identify partitions on those drives. Windows uses letters like C, D, E etc to identify drives, partitions and devices which can make things complicated for new Linux users.

Re: no option to boot to linux

Do you even get the GRUB menu when you boot? Also install partition editor to see if anything is detecting your second hard disk. But yes also make sure you BIOS settings are correct.

Re: no option to boot to linux

I installed partition magic and it shows the second hdd and it shows linux on it. What kind of bios settings do i need to make? right now I have hard drive set as first boot option. and I don’t see grub start at all just goes straight to windows. I have three hdd’s installed if that makes a difference.

Re: no option to boot to linux

I don’t know much about booting when it comes to multiple hard-disks. But, I guess this may help you:
1. Boot using Kubuntu Live Disk
2. Open Terminal and type

sudo grub //specifying boot directory
grub> root (hd1,0)
grub> setup (hd1) //installs GRUB at MBR
quit

3. Change name of your menu.lst file (must be in Linux partition of Disk-2 with /boot/grub/menu.lst) to menu.lst.backup
4. There you create a new file named menu.lst and write:
(But, if your hard-disk is ‘hd’, then use ‘hd’ instead of ‘sd’ , and write proper files names of vmlinuz* and initrd* by looking in your /boot directory)

default saved
timeout 5
fallback 0
title Kubuntu @ /dev/sdb0
map (hd0) (hd1)
map (hd1) (hd0)
root (hd1,0)
kernel (hd1,0)/vmlinuz-2.6.24-23-generic root=/dev/sdb0 ro quiet
initrd (hd1,0)/initrd.img-2.6.24-23-generic

savedefault 0
title Windows @ /dev/sdc0

Re: no option to boot to linux

Have a closer look at your bios: Some bios have a separate setting where you can choose the boot order of the individual hard drives.

But if you cannot change the boot order in the bios, then I suggest to get SupperGrub

Follow the direction from this page:

Try the «Windows Solution» first. If that does not work, try the «Quick Solution» and then the «Not So Quick Solution»

munishvit’s directions will only work if you can set your bios to boot from the Kubuntu drive. But in that case you might not have to reinstall grub anyway. So I wouldn’t use the LiveCD to reinstall grub at this stage. (But you might have to do it later)

Do not edit the «Kubuntu» part of menu.lst. It is extremely unlikely that there is anything wrong with that part of menu.lst
You probably will have to edit the Windows item. But I wouldn’t worry about that until you are able to boot into Kubuntu.
