• Winusb doesn’t support windows xp.so follow the simple steps given below,
• Download multiboot,and then follow this guide to make bootable windows usb.
• Already tested Windows XP, Ubuntu and Windows 7.

i’ve tried using winusb before, but i still got the same error message after it was done. i’ll try it again though and give you the results.

If I understand correctly, after trying Ubuntu, you want to reinstall Windows XP. You were trying to simply copy the contents of the Windows XP Installation medium to a USB drive and got a «BOOTMGR missing» error when trying to start the computer with this USB drive.

My first idea was to replace the boot sector on the USB drive with a Windows XP boot sector, which would try to load NTLDR instead of BOOTMGR. However, this failed to take into account that with either boot sectors (older XP version or updated Vista and newer version) the Windows XP Installation medium is not designed to be started from USB (unlike that of Windows Vista and newer).

From other comments that you made, I seem to understand that you do not own a physical copy of your Windows XP installation medium, but rather have an ISO copy of it.

The logical advice from here is simply to burn your ISO copy to a CD-ROM and to use that disc to start the computer and install Windows XP the way it was designed to be. This solution does not seem to appeal to you. Maybe you don’t have a CD-ROM drive or burner in that computer?

BOOTMGR is missing при установке с USB-Flash

Выбирал дистрибутив чтобы поставить на ASUS EeePC 1015bx Что ставить новобранцу?. Но вот же незадача. Столкнулся с новой проблемой. Делаю загрузочную флешку. Т.к. сегодня ни у кого из ближайшего окружения не нашёл компа с линуксом способ http://habrahabr.ru/post/53219/ отпадает. Решил воспользоваться unetbootin-windows. Вроде все ок. Загрузочная флеха готова. Однако, как только начинается загрузка с флешки — опа: BOOTMGR is missing, Press alt+ctrl+delete to restart.

Думал может на дебиан ругается, писали что с ним могу проблемы быть, но не тут то было c xubuntu 12.04 такой же «пирог» получился. Кто знает как бороться?

BOOTMGR это же вендовый загрузчик.
Честное слово не знаю что у вас там эти унетбутины записывают, неужто он виндовый загрузчик туда запихал для запуска установщика линукса.

По-моему самый разумный вариант: установить загрузчик ручками, положить туда установщик и данные.
Вкратце:
1) качаешь загрузчик, т.к. ты пользователь винды, то советую grub4dos
2) качаешь установщик
3) записываешь на флешку бутсектор (в наборе должен быть ехе для этого), и кладешь в корень grldr menu.lst vmlinuz initrd.gz и скачанный ISO-образ дебиана
4) в menu.lst вставляешь:
title Debian Squeezy Installer x86
kernel /vmlinuz
initrd /initrd.gz
5) загружаешься, устанавливаешь, добро пожаловать!

К слову так же просто можно запустить установку с обычного hdd. Самое главное этот способ прозрачен и результат предсказуем, в отличие от этих мутных утилит, которые непонятно что делают.

Unetbootin не работает с NTFS.

записываешь на флешку бутсектор (в наборе должен быть ехе для этого)

Тот, что там есть, работает только под DOS и Linux.

Thread: Bootmgr is missing

Bootmgr is missing

I am trying to install Ubuntu on my computer on which previously Windows 7 was installed. I am using a usb stick which I have already successfully used for installing Ubuntu on another machine. The installation works fine and I erased the whole hard drive, but when I reboot the message «bootmgr is missing» is shown.

I have used boot-repair and this is the file it gave me: http://paste.ubuntu.com/p/ZQtNSDYPNh/

I would be happy to get some help.

Re: Bootmgr is missing

You did not install the Ubuntu Grub bootloader and have windows boot code in the MBR of sdb, the 300GB drive. That drive has only one partition and it is a windows filesysterm so you haven’t installed Ubuntu anywhere. When you install Ubuntu, make sure it is pointing to sdb (300GB drive) and make sure you install Grub to the MBR. It should detect your windows and create a menuentry in the Grub boot menu.

The error: bootmgr is missing is a windows error as the file bootmgr is a windows only file. Boot repair generally shows the Ubuntu and windows boot files but it doesn’t show your windows boot files?

Re: Bootmgr is missing

Thank you for your reply. I guess I made a stupid mistake and left my installation usb stick in the usb slot. Now after I removed it the system starts perfectly fine.

But I have one last question:

I executed boot-repair again and I am wondering whether this might cause problems:

Re: Bootmgr is missing

Not sure what your question is. You have windows code in the MBR of sdb and a windows system installed on sdb1, first partition of that drive. That’s the way it should work. The only other drive showing is your usb/flash drive with the Ubuntu installer.

OK, I just took a look at your new boot repair link. You made a mistake of installing Ubuntu UEFI while you have windows 7 as a Legacy/MBR install. You either need to reinstall Ubuntu in Legacy mode or when you want to boot windows, you will have to change boot priority in the BIOS each time.

You might take a look at the Ubuntu documentation below which tells how you will know if you are booting in UEFI mode or Legacy mode. It also explains converting from EFI to Legacy mode which might be easier than installing again.

Re: Bootmgr is missing

Actually there is no Windows 7 installed on the system anymore. I erased it from sda, where now Ubuntu is installed.

So I thought when I erased Windows 7, which indeed was using the BIOS mode, my system is ready to install Ubuntu in UEFI mode.

From my last boot-repair report (http://paste.ubuntu.com/p/xz4vwwvPdq/ yesterday’s report) It seems for me that sda now looks fine.

But the following lines made me a bit worried:

Do I need a boot loader there?

Will this cause problems? Or should I replace it?

sdb1: __________________________________________________ ________________________

File system: ntfs
Boot sector type: Windows 7/2008: NTFS

Should I use a different file system or is ntfs fine? Will it cause problems that Windows 7/2008 is the boot sector type?

Thanks for your help so far.

Re: Bootmgr is missing

BIOS boot uses MBR, UEFI boot uses the ESP — efi system partition, so no UEFI boot files in MBR.

Having a BIOS boot loader in MBR is not an issue unless you attempt to boot it and the rest of the system is not there. If later you install another system to sdb in BIOS boot mode it will overwrite the code in the MBR.

While you can use NTFS, evenually it will need defrag and if incorrectly unmounted or other issue will need chkdsk. Neither of those fixes can be run from Linux. Or you should have Windows if using NTFS or at least a Windows repair disk so you can run repairs.

Re: Bootmgr is missing

Thank you oldfred for your background information.

To be honest I feel not comfortable using NTFS, since I also heard that it might be not the best choice for Linux.

Now nothing is stored on that hard drive yet. Even though I do have a Windows 7 copy I feel better with changing the file system.

Can you tell me how I can do this or what guide I should follow? If necessary I can reinstall the whole system.

Re: Bootmgr is missing

You have UEFI hardware, so probably better to use UEFI install.
How you boot install media UEFI or BIOS is then how it installs.

Shows install with screen shots. Both BIOS purple accessibility screen & UEFI black grub menu screen
https://help.ubuntu.com/community/UEFI

Lot more info in link in my signature below (perhaps too much).

If new user a default install, but not using LVM nor full drive encryption as LVM is an advanced volume management system. Mostly for servers, but required if you must have full drive encryptions. It erases everything.

Default install of 16.04 uses just / (root) and swap. Newer versions do not create swap partition, but just have swap file. If UEFI you will also have the ESP — efi system partition, typically as first partition. Drive has to be gpt partitioned, not the old MBR(msdos) partitioning.

BOOTMGR is missing after re-enabling GRUB

Here’s my scenario. My laptop originally had a 40GB hard drive (it’s a 2005 IBM Thinkpad G41), and that simply was too small so I bought a 160GB drive. I used partimage and backed up my Ubuntu partition to a USB hard drive, installed the new drive, and restored the partition. Then I setup 2 more partitions for Windows installs. Here’s how it’s laid out.

hd0,0 — Ubuntu 9.04
hd0,1 — Windows 2000 (for WoW only)
hd0,2 — Windows 7 RC

After copying the Ubuntu partition I installed Win2k, then Win7RC. With the MS bootloader I could boot Win2k and Win7RC without problem. I wanted to get my Ubuntu back, and prefer GRUB so I used the GrubHowTo in the Ubuntu docs to re-enable it. After enabling GRUB, Ubuntu boots fine (partimage is FTW) but when I try to boot Win7 it gives me the annoying error below:

I’d like to be able to use Win7 to test on our domain at work, and it actually runs quite well on this old laptop. Please offer some suggestions for how I can fix this!

Re: BOOTMGR is missing after re-enabling GRUB

I booted up SuperGrubDisk, selected Windows, then selected boot Windows from 2nd Partition (Laptop) and the Windows bootloader started, allowing me to boot either Win2k or Win7RC.

So. since I know that this works, can someone please help me get it to work with the GRUB I have installed on my MBR so I don’t have to boot from the CD every time I want to use Windows?

Re: BOOTMGR is missing after re-enabling GRUB

I found your thread earlier when I was having this exact scenario earlier today.

Just now I realized that Win7 creates at least 2 partitions when you install it, even though you may have only one selected and formatted for it’s use.

Basically, from what I gather there should be a partition of around 8MB just before or after the actual installation partition for 7.

So, all you have to do to fix this issue is change your target drive for the Win7 OS to the 8MB partition that sits somewhere near the Windows 7 partition.

Try checking our your GParted list of partitions, or if handy with a CLI, use fdisk to check out the list of partitions and their sizes. You should find one with a very small capacity formatted as NTFS.

In my case though, it was before Win7 install parition. So, I had done all this before-hand to determine the install partition, and of course pointing GRUB to this install partition yielded only «BOOTMGR not found».

For me, simply changing (hd0,3) to (hd0,2) resolved my problem.
