Don't like how ugly your PC looks when you dual boot? Customize how your computer boots with Grub 2 - ||Join the chat: http://on.fb.me/follownix || In this tutorial I show you the basic ways to configure your bootloader. Lots of things have changed since the upgrade from the original Grub, so check out this week's episode of OS.ALT to learn more about how to make your boot menu boot-a-licious!

I have dual boot Windows and Linux Mint 18.1 xfce and I want to know where is grub2 physically stored and the HDD my Linux Mint is installed an SD A6 so is that where the grub2 is my computer is MBR and I believe my MBR code points to the grub2 but I want to know where and the drive is grub2 in a separate partition or within SDA 6 and I thank you very much in advance
have an issue on no graphical mode boot
debian doesn't boot on desktop (kde ou gdm3)
i reinstall gnome and xfce kde and gdm3
but nothing after an dpkg reconfigure
what your solution when startx doesn't work ?
I use bionic beaver and I dont think much has changed. mostly because this tutorial is about GRUB which has basically nothing to do with your linux. its just the thing that starts your linux. but it could be possible that newer ubuntu uses a newer version of GRUB so your question is not completely obsolete. so yes: I'm pretty sure it should work in 17.04
Gr8 Tutorial.. Are you able to share, how to add a Freebsd UFS and/or ZFS entries to grub.
BTW would you consider doing a tutorial on rEFIbd boot loader.
Thanks so Much!
Both your mind & body is so captivating ! 10 + on all counts.
i am facing a problem with booting to win 10 after Zorin os has been installed i can see the Win 10 loader option but when i use it it just refresh the boot screen to ask again the boot selections -_-
sorry if my English not good :)
I just dual booted Ubuntu14 alongside Windows 10 via a partition, and in Ubuntu my screen keeps flashing black+white as if thiers an interpretation error with the Graphics Card. I need 14 for the software I'm running so I need a fix that doesn't require updating the OS. Any ideas?
I have successfully installed Ubuntu Mate 16.04 LTS on my Mac Mini as a
dual boot system. I also got rEfind installed manually on my Mac. The
thing is that rEfind can't seam to boot Ubuntu. I did figure out how to
boot into it from a recovery mode in Advanced Systems. I have it all
setup, and it is working well, except for that. Do you have any sage
advice that could help me solve that boot up problem? God Bless.
Grub shell. I could get to know how to set pager environment variable (set pager=/bin/more ...yes, got to provide full path to "external" commands...)
No CD command available. NO TEXT EDITOR ALSO. I barely could to see dmesg log file., no kernel panic warning but system boot up stalls.
Grub shell help needed!
What exactly is non-techy about Ubuntu? Linux is Linux, the only thing that really separates distros are repos, desktop environments and pre-installed apps. Even though Ubuntu might not directly appeal advanced users it's a perfectly capable OS for "techies" or whatever you wanna call yourself. Aaaaaand, Linus runs Fedora, thought everybody knew that?
How do I get bootloader from USB drive to my Hard Disk? I don't have a bootloader on my hard drive (i.e. no other operating system - i.e. no Windows) and Ubuntu won't boot from the hard drive (only from the USB drive). When I try and boot from the hard drive (with no USB drive attached) I get the message: "no such file or directory as /boot/efi - I suppose I need to somehow transfer the EFI Boot Loader from the USB drive to the Hard Drive. Can any kind soul help me with this - with explicit terminal commands as I am a noob to Linux. Many thanks - much appreciated - happy to send you a few hundred Satoshi's if you can help.
I am not asking what you did there, but how about this:
First find out what device that HDD is, I'll use /dev/sda as an example
sudo apt-get --reinstall install grub-common grub-efi-amd64 os-prober
sudo grub-install /dev/sda
But all this does is to copy the bootloader over and grub makes a reference to your USB-stick there, so you would boot from HDD to USB.
Does the HDD even have an OS on it, who Grub can boot into? You may consider installing an actual OS there, but if that HDD has data on it, I'd refrain doing so.
Great video! I just discovered this channel and am really enjoying it.
For those wanting more detailed info than a video will allow, IBM has a fantastic page all about Linux bootloaders and how to configure them.http://www.ibm.com/developerworks/library/l-lpic1-102-2/
well this would be very overkill especially because you dont install OSes on a regular basis. if you know you want both: first install windows than linux. if you already have linux and want windows: just remember that you have to reinstall your grub. no need for an overkill always search for new os grub thingy. and I'm pretty sure there wouldnt be an easy fix to achieve the behaviour you specified
Grub, by default, detects Windows and put them in its list automatically when it (Grub) is installed with Linux installation. As it seem (I did not know that till now) Grub cannot do that when Linux is installed prior, only because it is not possible to know that it has to search for another OS (Windows). As it seems it is programmed to search for another OS during its installation. After that, in order to see Windows, it has to search for another OS all the time, as it does not know when to search for another OS. Maybe it could be possible to be programed to search for other OS every time it starts and show the new entry in the next boot, but I don't know if it is possible. I think, maybe nothing of what I say is right, that what you did was just to force Grub to update its list settings and maybe, if you are in a UEFI system (UEFI motherboard, both OS installed in UEFI mode and not in BIOS Lgacy, and so GPT partitioning style), force it to have a look at EFI partition, find there the windows boot information that informed Grub itself that there is a Windows boot - loader in your hard disk and finally search, found and put WIndows boot - loader to the Grub list.
I want to change my grub menu or hide it. Because it turns out that if I perform a very simple edition in the kernel while the system is booting up..,vualá: I am the root user without type any password or I can change this password! It seems to me a huge security breach
You can password lock grub in such a way that only the default entry is accessible unless you have a password. Booting another entry or editing an entry will require a password. You can password protect all entries too.
Then the next question is:
What if grub.cfg has been modified?
You can generate a standalone image of grub that contains the grub.cfg. If you have a UEFI PC, you would be able to sign the stand alone image, store the public key in the UEFI NVRAM and enable secure boot. You can then store the keys on an encrypted disk or partition that you have to unlock manually when you want to modify or update grub. So unless you unlock the encrypted drive, nobody will be able to fiddle with your grub unless they have time to factory reset your UEFI and remove any password that you use to protect the UEFI.
It is possible to make grub secure where it would require physical tools to change the boot options, but this would take some time and won't always go unnoticed. So all that remains is physical security.
Always require a password for sudo.
Always lock the screen when you won't be keeping an eye on it.
Lock boot order in the BIOS/UEFI.
Password protect BIOS/UEFI setup.
Enable tampering protection so that if someone physically opens the computer, they would need to know the password upon next boot or they would have to figure out how to reset the EEPROM before they try to boot after tampering with the computer.
Remove all other boot entries and disable the possibility to boot removable media.
To make secure boot work with custom images, get your hands on GNU's secure boot tools.
If you want to have a secure laptop, buy a laptop that supports secure boot, boot order locking and tamper detection.
Never downplay the importance of physical security, it goes a long way!
I wouldn't call it sexist. It's presumptuous, and based on the fact that it's hard to find women interested in deep tech topics (not that I would even consider this video anywhere close to a deep-tech topic). But regardless, I agree with the sentiment of your comment, Christaliana. There's no good reason to assume the person in this video isn't actually competent in tech.
well as a girl I know more about linux than many of my guy co students. even my boss and co worker asked for my help because I knew more of linux than they did. so take your sexist comment and stuff it up deep into...
But where the hell do you get all this info.
You yourself must have read the content of these videos somewhere or the other.
I mean your source of info.
Please suggest some reliable source. Please. _/\_
doesn't have a lot options but it is pretty usefull:
''sudo apt-get install startupmanager''
nice manager for grub as well as burg:
''sudo add-apt-repository ppa:ingalex/super-boot-manager''
''sudo apt-get update''
''sudo apt-get install super-boot-manager''
At the risk of sounding like a n00b, is grub 2 a part of Android? At the moment I'm more interested in rooting my phone and would like to know if this lesson would applicable to a custom Android device/OS.
More people should use EXTLINUX as their primary bootloader for x86 boxes. It's a very elegant bootloader. I can build my own configuration file in one place and the bootloader doesn't care about drive ordering, which is a real win for a thumbdrive junkie like me. And since SYSLINUX and ISOLINUX understand all the same stuff, I can rename the configuration file and keep my config no matter what file system or medium I am on. Nixie should give this bootloader a try.
Yawns... Lilo.conf anyone? Anyway, Grub is cool. I normally just use it anyway. /boot/grub contains the good time grub boot custom options, and if you run into a realllllly messed up problem, like the /boot/grub directory ending up in /home/yourname/boot/grub(why I don't know? Maybe you rolled your own and the stems stuck out of the rolling paper), that would be the file you'd want to look at. The .mod files have to do with options passed to the kernel and other kernels and os's.
@nixiedoeslinux i don't know if you also find an interesting issue: when having both Ubuntu and Debian installed in different partitions, Ubuntu doesn't include Debian on the grub update, but Debian includes Ubuntu - very weird, isn't it? when you have opportunity to try it, please do, i think you'll be shocked as i got
