Error message 0xc00000001 while booting Windows 8 after installing Ubuntu

Question

After I installed Ubuntu 14.04, as I switch on my computer I only receive one message which is:

Windows Boot Manager, Windows failed to update: status 0xc00000001

What should I do?

Answer 1

According to NeoSmart Knowledgebase (creators of EasyBCD):

Fix 0xc0000001 in Windows 8

Windows 8 users may fix this boot error without an installation disc by using the Windows Startup Settings (see Fix #1 below).

Fix #1: Use Windows Startup Settings

1. Restart your computer
2. Press SHIFT + F8 when booting to open the Recovery screen
3. Select the Advanced repair options
4. Go to “Troubleshoot” and then “Advanced Options”
5. Select Windows Startup Settings
6. Click on Restart

Reinstalling Windows Boot Manager with new BCD

If that doesn't work for you, you probably have invalid BCD data after moving partitions. You can fix this by creating new BCD data with bcdboot from another Windows 8 installation, Windows 8 installation media or Windows 8 Recovery Disk. Have a look at the NeoSmart site, you will find Recovery Disks there. The same works for other Windows versions accordingly.

Using the bcdboot command isn't very complicated:

bcdboot C:\Windows /s S:

This example taken from the Technet page about bcdboot would install from current C:\Windows source to drive S:. S: should be the drive with the boot flag (1), which is usually called System on OEM installs, so S: may be correct.

As far as I know bcdboot is only available on Windows 7, Windows 8 and above. (Don't ask me for advice on EOL software.)

Reinstalling GRUB

Since this will overwrite the MBR on a computer with an old partition table, you will need to reinstall GRUB, to be able to boot Ubuntu again:
