Something's strange with my computer. Just today, I had to do a battery swap.
Like always, the system is always turned off when the battery is swapped.
Before the battery swap, both operating systems worked fine; both can boot normally.
However, when I turned the machine back on, both of my operating systems (Windows 7 and 8) failed to boot. It would bring me to a Blue Screen of Death, but this BSoD would not show any information, but instead flash, disappear and trigger a reboot back to the main boot menu.
Note: THIS HAS NOTHING TO DO WITH A FAULTY BATTERY (or hard drive)!
What I tried:
I went through my computer information/configuration, and there seemed to be nothing wrong with my BIOS.
I then booted (just to make sure) Windows 7 and 8 normally. Neither worked. All I received was a lightning quick BSoD that I could not capture any infromation from.
I then went on to attempt to boot into safe mode. Strangely enough - Windows 7 failed to boot at
classpnp.sys while Windows 8 booted safe mode fine.
After restarting again, Windows 8 booted normally for safe and normal mode, while Windows 7 could not boot at all.
However, whilst in Windows 8, I have noticed that the time has not moved at all; it was still at the time of my last successful shut down.
I then tried restoring back to a previous system state (for Windows 7) using recovery mode, which works correctly.
Sadly, there wasn't a recovery state I could use. So I tried the "System Repair" Utility.
After 5 minutes, it stated to restart the machine and "everything should run as per normal as repairs are complete", but it still gave a BSoD.
After browsing some other sites, many people deduced it as a faulty disk.
But recovery mode for both Windows 7 and 8 worked fine. Even the boot menus (for both operating systems) successfully loaded, which means it isn't a faulty disk.
- If it had nothing to do with corrupted system files, what could be causing Windows 7 to be unable to boot?
- And because I was able to fix Windows 8 without re-installing (any recovery/install media/drives), is there any way to do the same with Windows 7?
Summarize of what works (as of the asking of the question):
- Windows 7 cannot boot into safe or normal mode.
- I do not have any Windows 7 recovery media.
- Windows 7 and 8's recovery mode works fine.
- My Windows 8 recovery media is on another partition (but for some reason inaccessible through the boot menu)
- Windows 8 now works perfectly fine.
