[SOLVED] Bios won't boot from freshly installed OS on new hard drive

[Grimee]

Hi,

Recently i've installed a fresh OS, windows 10 on a new HDD.
The problem is, bios would only boot from my 2nd HDD where i got windows XP and only then gives me option to get to windows 10.
If i choose boot priority my new HDD where i have fresh windows 10 on it, it gives me NTLDR is missing.
What can be done?


Thanks

Give specs of ur system.
Socket, cpu, ram, etc.

Motherboard: ASUS P5QL PRO, Socket 775
Intel Core 2 Quad q8300 2.50 GHZ
4 GB DDR2 Ram

Windows 10 on socket 775.
Yep.
I gotta try this on my older dq45cb mobo, but windows 10 isn't always the best idea on older sockets.
Next to try is to remove the XP-drive with its connections, and run the system only with the windows 10-drive.
If it fails again, try reinstallation.

Redo the WIn 10 install.
This time, with ONLY the desired drive connected.

Is there anything else that can be done before doing it from the scratch, maybe rebuild MBR or that wouldnt be a good choice?

Nope it's same, with only windows 10 HD connected to the motherboard, gives me same, NTLDR is missing...
Seems the drive with the win 10 depends on first drive with windows XP in order to get in lol

Next step: Reinstallation. Format the drive fully before it.

If it fails again: Partition the drive, that already has XP in it, and in the new formatted partition install the OS. And boot from it (select OS afterwards).

Meanwhile update bios if not already done so.

Is there anything else that can be done without going through the whole process again? Maybe rebuild MBR ?

I just am trying to help you with things I 've already done in similar situations of mine.
Things like rebuilds/Windows restore/etc still have risks of computer going slow afterwards, with errors and such.

Full wipe and reinstall, on the single drive.

Rebuilding MBR didn worked, only clean install did yes with the first HDD win XP disconnected as advised, now both drives boot to their own OS independently.
Thanks!

No doubt, rebuilding MBR didnt worked. Clean install did with the first HDD win XP disconnected as advised, now both drivers independently boot to their own OS.
Thanks!
