Black screen, blinking cursor
I have already posted at the Expert Exchange, but I am getting no traction there so I am thinking of reposting here.
All the tech spec are in my post below, but I wanted to summarize the problem so that it wasn't such a chore to read:
Basically, I had 3 drive, each with one OS: Win XP, Vista 64 and Win 7 64
For some reason the Drive with XP crashed and it's dead. Now I am trying to revive my Win 7 Disk but all I get is the same blinking cursor on a black screen. Each time the repair disk that came with my Win 7 upgrade tells me that everything is OK but each time I try to reboot I end up on the blinking cursor.
The reason the machine crashed is pretty clear: The win X{P drive was booting the rest of the OSs. Now that's gone the Vista and win7 drives don;t have a valid boot loader. The repair disk seems to think everything is fine, but it isn't.
It has been suggested to me to use BCEDIT : BCDEDIT - How to Use
But in iorder to use it it would have to be installed on the disk.
Does anyone have any ideas? Thank you.
My original Post from EE
I have had my rig for almost 3 years. It started out as a
Systemax Venture VX2 -
Processor: Intel® Core2 QUAD Q6600 @ 2.40GHz (2397 MHz)
Motherboard: Intel DG965WH ATX Motherboard w/Gigabit LAN
Passed thought
Vista Ultimate 64 bit with 8GB on a dual boot
and finally ended up as a :
Windows 7 Professional, 64bit, 8GB (OCZ Vista Upgrade Edition Dual Channel 4096MB PC6400 DDR2 800MHz)
Each OS has been mounted on its own Hard Drive. As I upgraded I kept the OS and the Drive and added a new one.
Yesterday morning, I sat at my desk and a blank screen with a blinking cursor at the top left corner welcomed me.
INITIAL SYMPTOMS:
upon restarting the BIOS screen came on but it was frozen. There is a number on the lower right corner of the BIOS screen that usually runs by, but it wasn't moving. Basically, there was no sign of intelligent life in there. No F key had any effect on anything. (F2 should take me to setup)
I am not a total moron when it comes to hardware and software and I have a friend that does this for a living so I called him.
We first tried the obvious, to no avail. Then we started taking everything off the rig so it would run as bare bones as possible. No Video card, no peripherals, no modems, etc.
Finally, I reset the motherboard with the jumper. After that at least I was able to go on to the dreaded blinking cursor, but more importantly I was able to get to the BIOS set up screen.
There I realized that we couldn't see any of the drives. We went through a few more setting in the BIOS (I am making this as brief as I can) until I decided to make it even more bare bone. I unhooked everything inside and changed power supply with another computer I have. Power supply was OK and I started running 1 hard drive at the time against the BIOS screen. This is where things started getting interesting:
These are the drives I had in the machine at meltdown time:
1) Seagate Velociraptor, 10,000rpm with Win 7
2) Maxtor 500GB with Windows Vista 64
3) Maxtor 250 GB with Win XP pro
4) Seagate 1.5TB no OS (This is my document drive - I keep no documents on my OS drives)
Running each drive separately gave me some interesting results:
1) Seagate : Could not see in BIOS and got blinking cursor
2) Maxtor 500GB : Could not see in BIOS and got blinking cursor
3) Maxtor 250GB : Could not see in BIOS and got blinking cursor
4) Seagate 1.5TB could see but got "No Operating system error" when trying to boot up (for a time I was not sure which was which because it was cramped in there but I kept notes)
So at this point I run to Fry's and I bought a SATA enclosure to see what the drive's were doing.
I attached the drives to both my Mac and my Laptop with Vista. These are the results:
1) Seagate Velociraptor: Run fine all files safe and sound
2) Maxtor 500GB with Windows Vista 64: Run fine all files safe and sound
3) Maxtor 250 GB with Win XP pro: Run but did not mount. On the laptop actually made a clunking sound
4) Seagate 1.5TB : Run just fine
At this point it was clear what happened:
1) For some reason my oldest drive failed
2) Since I installed 3 OS on top of each other, the Win XP disk actually contained the Boot.ini file that controlled the boot of the other drives. Once that was gone the other drives did not know where to boot from
3) This was confirmed by a later Windows repair I performed were both the Vista and the Win7 drives resulted having missing or corrupted Boot files or sectors (I wish I kept better notes - more on that later)
Once I figured all that out, I tried again to mount my OS disks in my rig, minus the XP disk. Once again I get the blinking cursor but at least now the BIOS is able to see them all.
I have now repaired the Win7 disk several times:
1) At first windows repair fixed it and made me restart without giving me any choice in the matter.
Result: black screen as before
2) The second attempt it let me choose the repair method. I choose to perform a repair (first choice in the repair window) and came up with an error saying that the boot files (or sectors, or blocks) were corrupted or missing and that it fixed them
Result: Ditto
3) The third time, far from being a charm, I performed the repair again and I got this:
Boot selector code for system disk partition is corrupt
Repair Action: Boot sector repair
Result: completed successfully Error code= 0x0
But it didn't work. Whenever I try to boot I still get the dreaded black screen with the blinking cursor.
My next step is to go ahead and perform and more complete repair of the installation. But before I do that, at the risk of messing things up further, I wanted to ask people here if anyone has had any experience like this and what you have done to fix it.
At some point we thought the SATA channels were bust, since we couldn't see the drives (all but one). but that is no longer true.
I know that I am spent. Thank god I have my Mac and my laptop that are both pretty powerful machines, so I can continue to work, but most of my software is highly tricked out and set up "just so" working on a backup machine, even if 80% of the software is the same, takes me a lot longer.
