Cant boot into Windows 8.1(which is pre installed) after dual boot installation of Fedora 25 (installed in Legacy mode). Error says Boot Configuration Data is missing

asked 2017-08-15 09:23:16 +0000

I recently installed Fedora 25 in my Lenovo PC which came with Windows 8.1 pre-installed (most preferably installed in UEFI mode..Laptop is 2yrs old).

This is the sequence i used, to install Fedora.

  1. Made a 117 gb of unallocated space from a drive using "Disk partition" in windows 8
  2. Created a bootable usb of Fedora 25 using Fedora Media Writer downloaded from the website.
  3. Turned off the secure boot mode and changed the settings to Legacy (wherever found this option)
  4. During installation i selected the drive of 117gb to install the fedora and installed succesfully (in legacy mode).
  5. Restarted the system. A menu appears with 4 options. 5.1 Fedora (4.8.6-300 and so on) 5.2 Fedora (0-rescue and so on) 5.3 Windows recovery environment (loader) (on /dev/sda3) 5.4 Windows 8 (loader) (on /dev/sda5)

    The problem starts here.. When i select first option Fedora boots up with no problem. But when i try to go for Windows (last option) it shows an error.

"Windows fail to start" fie :\Boot\BCD Status : 0xc0000225 Info : The boot configuration data is missing.

But when i use fedora i can see all my drives including the drive which has windows installed. Please help me solving this error and the main problem is I'm completely new to Fedora.

Step 3 killed the windows, it wants to boot efi and you disabled that. You would need to install fedora with efi enabled to keep the windows working properly.

Reverse what you did in step 3, and boot the usb, using efi to install fedora. the usb should be detectable with efi enabled. you can leave secure boot turned off, if you want, but set the boot mode to uefi in your bios. follow the installation of fedora, and when it asks about where to install, select the option to make space available, delete the partition that has the legacy fedora, and let fedora installer create new partitions. Should be simple after that, just do the install as you did it before.

Im sorry but i dont understand this part "then it asks about where to install, select the option to make space available, delete the partition that has the legacy fedora, and let fedora installer create new partitions."

you are saying that after booting up the USB i should select the drive that has legacy fedora to reinstall???

or

should i be clearing space before booting the usb for fresh installation???

you can do either one. installer for fedora can clear the space, or you can clear it before you start.
