I'm running Ubuntu Studio 18.04 and Windows 7 in a dual boot.  Ubuntu needs 2 boots to finally working, it sometimes gets stuck on the first attempt by showing strange lines of color artifacts on a black screen.  Using Boot-Repair I understand the procedure of creating a new partition at the beginning of the disk, which I have already done, but I noticed that the first OS on the disk is Windows. In fact, I recently uninstalled Ubuntu 16.04 and replaced it with Ubuntu Studio 18.04.  Is this the problem, you think? and if so, can I solve this without erasing everything and starting from scratch? My copy of Windows is very old, and it would be hard to get it back.

I bought my PC with Windows 10 on it, later installing Ubuntu for dual-booting. Recently, I wanted to replace the HDD inside with an SSD of the same size, so I copied all the partitions to the SSD (GPT partitioning) using GParted and installed the SSD in the laptop. On startup, GRUB is loaded and I can:  Boot Ubuntu normally Select the &quot;Windows Boot Manager on /boot/sda1 or select bootmgfw.efi manually, however it loads a Recovery BSOD, stating the following with options to access the recovery environment (F1) or boot parameters (F8) but those don't work (same screen): File: \WINDOWS\system32\winload.efi is missing or broken Error code: 0xc000000e    As I understand it, Windows Boot Manager is loaded but cannot find the Windows boot loader (probably because not looking into the right partition), so what I need to do is give the right partition to the boot loader, but I have no idea how to do that. How do I fix this, preferably something that can be done from Linux and doesn't involve a reinstall of Windows?

I booted from the Ubuntu ISO which I burned on a disk and installed Ubuntu, and chose the option to replace windows 7 with Ubuntu, now the version of windows 7 I was running was an illegal cracked version and I already had tried to get rid of it without booting into the actual OS and after many attempts was unsuccessful. Now did installing Ubuntu and choosing the option of replacing windows 7 actually solve my problem and did it wipe the previous windows OS EVERY LITTLE PART OF IT.

I'm having a problem installing Ubuntu 12.04 on my ASUS UX31A alongside Windows 7; I tried to launch os-prober in my terminal and the only option I get is:   /dev/sda5:Windows Recovery Environment (loader):Windows1:chain   while Windows 7 (mounted on dev/sda3) is not shown.  This is what I see in my Disk Manager in Windows 7:    C: basically is the partition with Windows system's file, while the D: one is for data), while this is what I see when I launch GParted:     May it be because Windows is installed on SSD? How do I know that? Is it safe if I proceed with the installation for computers with UEFI, SSD and HDD? I'm not sure that's my case.

I have been trying to install ubuntu (I tried 12.04LTS, 12.10, 12.10-secure-remix) using the wubi installer on Windows 8 and all the three times ran into the same problem showing some cannot find /ubuntu/winboot/wubildr when I tried to start ubuntu.  I tried to change the boot settings from UEFI to Legacy and then my laptop restarted and showed that "No operating System Found".  I then tried to install Ubuntu using a cd and after a lot of effort and using boot repair,etc. I landed into a new trouble. When I select UEFI on, the laptop loads Windows and windows too does not detect ubuntu. When I select Legacy mode, it starts ubuntu, shows me an option to start windows 8 but gives an error showing windows failed to load.  So in legacy mode, i am able to use only ubuntu and in UEFI mode, I am able to use only Win8. Please explain any process of starting windows in legacy mode (which I tried without any success) or starting ubuntu in UEFI mode.

I've installed Ubuntu 16.04 LTS along side with Windows 10 (I shrinked my Disk using Windows Disk Management) on my Acer laptop (ES1-531-C13G), but when I restart/reboot my system no menu (Grub screen) appears from where I can select the operating system that I want to boot with, but instead, system takes me into Windows 10 everytime. I've tried several things from internet including :    Ran bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi from windows command prompt.  Reset  Bootorder i.e. first Ubuntu then Windows from Ubuntu terminal (after successful Ubuntu installation) etc, but nothing works for me so far. Please guide me !

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'm very new to Ubuntu, and have come to this point that I can't boot back to my Windows Vista anymore.  I thought that I would get some kind of dual boot in the beginning when booting my computer, but this doesn't seem too happen and I don't have the slightest idea on how to fix this. I was looking for help here at askubuntu, but I couldn't seem to find anything. I'm too new with this software.  I'll need hints and tips on how to fix this  Thanks for your time folks!

I had Windows 10 and Ubuntu 14.04 installed in dual boot.  Roughly 125GB each.   After the Windows update the PC only showed me the grub rescue terminal. I could neither use Ubuntu nor use Windows.  I inserted the liveCD and ran boot-repair.  After that Windows appeared normally, but no GRUB and no Ubuntu.  This is what I get when I run sudo fdisk -l:    Ubuntu must be either /dev/sda2 or /dev/sda4, since they are the biggest partitions, but neither of them is recognized as a Linux system.  What should I do?

I just installed Ubuntu, a full install removing the prior OS. I was forced to remove  from my  because of the max four partitions already being there. I didn't lose anything, all backed up. However, now I am looking to create another partition and install Windows&nbsp;7 on it.   Do I also need some sort of boot loader that lets me choose which to boot?

I'm a new Linux user. I've reinstalled my Wubi from scratch at least ten times the last few weeks because while getting the system up and running (drivers, , etc.) I've broken something (X, grub, unknowns) and I can't get it back to work. Especially for a newbie like me, it's easier (and much faster) to just reinstall the whole shebang than try to troubleshoot several layers of failed &quot;fixing&quot; attempts. Coming from Windows, I expect that there is some &quot;disk image&quot; utility that I can run to make a snapshot of my Linux install (and of the boot partition!!) before I meddle with stuff. Then, after I've foobar'ed my machine, I would somehow restore my machine back to that working snapshot. What's the Linux equivalent of Windows disk imagers like  or ?  Note: I found a similar question:

My computer is a Sony Vaio Notebook. I used Ubuntu and Win 8 with dualboot but windows somehow managed to remove the menu to choose the OS at startup. I think the BIOS is UEFI. Secure boot was disabled already and Boot Repair somehow fails.  How can I fix this?

I followed this  to install Ubuntu as dual-boot with Windows 8.1 pre-installed as(UEFI),but I am not able to dual-boot and tried    I first burned an Ubuntu ISO on a blank DVD-R to create the LiveCD. Even with secure boot disabled, when I tried restarting my computer, it never booted to the installation screen, and it just skipped to Windows.  After a lot of skimming, I thought I had to put my computer in Legacy Mode in order to get give my CD/ROM drive priority. I installed Ubuntu and used my existing EFI partition. Ubuntu works, but Windows doesn't, probably because my laptop is stuck in Legacy Mode. I tried switching back to UEFI using boot-repair on the Linux Terminal, and going into Advanced Properties -> Grub Location -> Ticking the checkbox for EFI, but it says I need to be in an EFI session, and now I'm just really lost and confused at what I've all done. I can see my Windows8.1 OS on a partition but I want to dual-boot Windows 8.1 along with Ubuntu?   Did I just brick my computer?

I have Windows 8 Release Customer Preview on my laptop. I tried to install Ubuntu on it with Ubuntu Windows installer (I have always used this to install, although that was on Windows 7), it installs and asks to reboot, then immediately Windows 8 boots up.  I do not have the option to choose what OS to boot. How can I boot to Ubuntu? VM is not exactly what I would like to use, but it is an option, however a last resort. Any help?

I'm new to how Ubuntu works and installed it yesterday alongside Windows 7, but in doing so I have created a few problems. I have partitions for Windows, Ubuntu, System Recovery, and storage for all my files with the intention to access them on either OS, but I don't even see all of my drives listed on Home Folder. Not to mention that  during the Ubuntu instillation I managed to screw up any chance of booting to the Windows side of things at all. I'll fix Windows once I get my hands on a copy in a couple days, but in the mean time any suggestions for accessing my files?  If you need me to find any data about my computer to help you figure out what's wrong with it, please don't hesitate to tell me what I need to show you. Thanks

I'm stuck on this screen. I've edited the Ubuntu boot partition while running Windows now Ubuntu does not boot anymore. In depth I have seen a lot of question like this one on here, but what I have not gotten is the replies from the people who have asked about whether the answer has worked or not. Basically tried to boot Ubuntu and it went well. It worked and I installed it something somewhere went wrong and now when I try to boot it. I looked at the other answers that said troubleshoot. So I did it ctrl-alt-1-7 but 1-6 just tells me to log in and runs a whole script than stops unexpectedly and 7 is where it says /dev/mmcblk0p2: clean Booting Ubuntu worked earlier (yesterday) but I trashed a file and then  renamed the file trash 1000 but kept the files so I renamed it ubuntu. Then I tried to restart it up on my Chromebook. It still has old entries from it but I don't know how to delete those to start ALL over. This on Ubuntu 20.04.
