So I had Windows 7 installed on my computer and I installed Ubuntu on a different partition and now it boots me directly to Ubuntu (after installing it) and I want to have a dual boot option!  How I do it? Do I need to use GRUB? And how that works?

I currently have Windows 7 on my computer and I want to install Ubuntu alongside Windows safely.  Could someone please provide clear instructions?

In theory, what I want to do is very simple, but I've done some google research and read some posts on this site and I'm still confused.   I want to keep win7 on my primary C:\ drive, and install Ubuntu (12.10) on a secondary drive (that I have yet to buy or install. I just want to be certain that I'm successful when I do this). If at all possible I'd also like it if when I start the computer I have the option to boot either Win7 or Ubuntu, like an account log in type thing where I just pick which drive I'm running with that day. And just to reiterate, I do not want to partition my C:\ drive or alter, change, or affect my Win7 system in any way.  The reason I'm still fairly uncertain about all of this, is that a lot of the guides I've read have been for earlier versions of Ubuntu. Also the vast majority of guides are about partitioning one drive to fit both OS'. I want two separate OS running from two separate drives that I can pick at boot. The guides I did find mentioned that there is some issue with the grub being installed on C:\ but the rest of the OS being installed on the other drive. Is this still the case? How do I avoid that?  Also, if it helps, I've been running 12.04lts on my laptop for a few months now in and out of class and I love it.  Finally, if you could please point me to a guide or write your answer in the form of a guide for a two year old that'd be awesome. I'm still an Ubuntu novice and I don't want to mess up my win7.

I have a HP laptop with Windows 8.1 and Ubuntu 14.04 dual booted. I used to use F9 key to enter boot menu and chose Ubuntu and then GRUB would appear where I would chose Ubuntu again. This was working fine all this while. Either a hardware change or a Windows update has caused the Ubuntu option to go missing from the boot menu itself.  How do I fix this and boot into Ubuntu again?

I have two systems installed previously Windows 7 and Ubuntu. I was trying to reinstall Ubuntu and format the Ubuntu OS partition using a tool in Windows 7.   When I have Ubuntu ready on a USB stick and restart my laptop, it prompts me with the GRUB rescue screen. If I boot from USB to install Ubuntu, it just hangs.   Anyway, I messed up everything. So my question is how can I boot Windows 7 now?

I have 2 1tb hard drives on my computer with Windows 8 on the first hard drive and nothing on the other.  I want to install Ubuntu 14 on the second hard drive. I've looked up some guides and they all say to install Ubuntu on the sdb partition when booting off a usb stick. I have also seen some say to unplug the Windows HDD and then install Ubuntu onto the second HDD, and Ubuntu will automatically detect Windows and ask what you want to boot into upon boot.   I am really concerned about this - Will it ask me to choose what OS I want to boot into? Is there something like rEFInd(Mac) for Windows? Can anyone please give me a guide on how to do it without ruining my computer?  Thanks

I want to install Ubuntu and learn Linux.  I've been using Raspbian a bit and really would like to get away from Windows as much as possible.  The only problem is some of the games I use requires Windows for now.  Also, I'm taking classes through Coursera and using online tutorials to learn Linux from and would like an operating system installed besides the Raspbian I have on my Pi.  I have a desktop computer with Windows 10 installed on a SSD (M.2 if it matters) and another HDD used to store files. I have a new 1 TB HDD I'd like to install Ubuntu on. My plan is to install it and place the GRUB bootloader on the new drive.  I can then point the UEFI to that drive as the primary boot drive and GRUB should allow me to choose Linux or Windows. My thought is if I do this, I can change the boot order in UEFI back to C:\ drive and have the machine boot directly to Windows as it does now. Then I have the option of having a dual boot system or a Windows only system. Is this viable?  Should I use the whole drive for Linux?    Also, I'm reading a couple different opinions on disabling Secure Boot and Fast Boot from the UEFI.  Any reason not to disable these in my plan above?  Any other advice is welcome. I appreciate the help!

I sometimes need Windows for some school projects. So I was thinking is there anyway to have both Windows and Ubuntu installed but automatically boot in Ubuntu but if i pressed F12 or just something when booting like when i'm going into the bios then i could choose between Windows and Ubuntu ?  EDIT: i installed windows now. And i wanna know how i wont see the grub loader when i boot and it just automatically boots into Ubuntu. And if i press and hold "Shift" i will see the grub loader and will be able to choose Windows

I have a PC with 5 hard drives (SSD and HDD). One of the drives has Windows 10. In the past, I have tried to install Ubuntu and Windows using the following method so there will be no interference between the two operating systems:  I Simply removed all the hard drives, except the one that I wanted to install Ubuntu, then install ubuntu and connect other hard drives. Then select the boot drive using the BIOS.  Can I do the same thing without taking out taking all the drives?  I mean I do not like  to see the GRUB on boot, I want windows to boot as default without the need for GRUB.

How would I go about dual booting Windows 10 and Ubuntu, the windows drive is on an ssd as my c drive and my s drive is a hdd that I want to use for Linux. I have no idea what I need to download it or anything.

I am a newbie in linux. I wanted to install ubuntu to my desktop. I currently have two partitions, Windows 8 in installed on one, and i have some important files in another partition. While installing ubuntu, if I chose "Replace Windows 8 with Ubuntu", do I lose the other partition too?   And are there other ways to leave the other partition as it is, and install ubuntu in the partition  where windows was installed.

Currently I am using a dual boot with Windows7 and Ubuntu 12.04LTS.  I would like to try Windows8. Not because I like it, but more and more people are using it.  I have created a partition where I would like to install it. I have only one physical drive.  What should I do to create a triple-boot and don't mess up my Ubuntu? This is my primary OS. But occasionally I need my Windows7.

I want to know if I will keep and still be able to use my Windows 7 installation after I use the Wubi Windows Installer (from ) to install Ubuntu?  Thanks in advance, Bas.

Is it really safe to choose the "Install Ubuntu alongside Windows" option from the Ubuntu installation program?  I never used that option, instead I used other tools such as partition magic or windows 7's disk tool to resize my partitions.  Since I'm going to install Ubuntu across a lot windows (XP, Vista and 7) machines. It would not be nice to damage those Windows partitions.  What is your experience? Can I use this feature without concerns?

I installed Windows 7, which ate Ubuntu's boot file. When starting up the computer, it now goes straight to Windows, without giving me the option of booting Ubuntu.   How can I get Ubuntu back?

A fair while ago (~ 2004) I was told to always create a separate partition for the boot directory.  And since then I always have.  But after reading a few questions about partitioning questions, I'm curious.  Do I still need a /boot partition?  Note:  If helpful, I'm dual booting (Win XP or 7) &amp; Ubuntu 10.04.  I also have one partition (using ext2/3) which I use to share files between the two operating systems.

My system has 2 OS: Win 7 x64 and Ubuntu 12.10. I'm getting 2 Windows boot options: "on dev/sda1" and "on dev/sda2". What does this mean? What implications does this have for my continued Windows usage and for when I may remove the Ubuntu installation later?  Longer: I was running just Win 7 x64, then installed Ubuntu 12.10 along side it. Was trying to boot back to Windows 7 only to get a "disc reading error." Booted back to Ubuntu, grabbed boot-repair, then used mbr repair in boot-repair. System could then boot back to Windows but in fact always did so directly, i.e. always by-passed Ubuntu. Then I used the Ubuntu LiveCD to get boot-repair and used the "Recommended" repair option. Now everything works normally except for the issue described here. Both Windows options in Grub boot to the same Win installation I had previously.  p.s. Running "sudo update-grub" maintains both the Windows options.
