K8N Will not boot a bootable CDRom

OK here is a strange one that I have not seen on the forum....
K8N with Retail 3400+ AMD Athlon 64 (CO stepping)
Sapphire 9800 Pro 128
2x512 OCZ 3200 EL (running 200mhz @ defaults 2-3-3-6)
2 X 150 GB Seagate SATA
200 GB Seagate EIDE 7200
MSI DVD 16x
MSI 52x24x52 CDRW
SuperFlower (TTGI) 450w SS power supply
NO OVERCLOCKING. ALL SETTINGS ARE AT DEFAULT/AUTO
BIOS recognises all IDE channels and devices when plugged in
Disabled SATA 3/4 in bios, SATA channel 1/2 appear
System above will boot to floppy and run MemTest overnight
Will not boot to known working IDE drive (Master on IDE Channels 1&2)
Will not boot Seagate CD Rom utility disk (to format SATAs)
Tried as both master and slave on both IDE channels
Will not boot Windows XP CD Rom (more on this later)
Locks up when loading DOS CD Rom drivers (no CTL+ALT+DEL breakout)
All parts (except MB and proc) run fine in my XP 2200 box.
Cleared BIOS, Flashed BIOS 1.1 and 1.25
upped RAM volts to 2.85
changed CAS to 2.5-3-3-10 (suggestions from OCZ)
put 1 stick of RAM in each slot
All same results. Lock up at loading CD Rom driver
Put in Kingston ValueRam (Kingston recommended for this board)
Same storyNow thinking power issues....
unplugged all but CDRW, same story
New Antec 500 W PS (borrowed) same story
Thinking problems with memory registers in processor....
AMD agreed, RMA'd proc with AMD
Got "new" processor back
Same exact thing
Borrowed K8T Neo FIS-R, plugged in above parts and it boots fine
I high level formatted one of my SATA in ~ 10 minutes. Discovered I had bad XP install disk , but rig with K8T will boot off the CD Rom with no issues.
Is this a nForce 3 issue I am seeing or a flaky board?
I have RMA with NewEgg, but any help appreciated if I can get this fixed before I box it all up......
jbe

Yes. I suspected the cables as well and put in a set of known working ones from my 2200+
I want to make it clear that when I put in the NEO FISR2 the only thing I changed was the motherboard and it booted.
I was hoping that I had overlooked a BIOS setting, but when it would not boot after clearing CMOS and flashing to 1.25 with "fail safe" defaults I gave up.
Board is on its way back to New Egg for exchange.
Thanks for the replies.....

T500 will not boot from bootable CDs/DVDs, but will read and open files on them

System: 2 T500s, both manufactured early April 2009, win XP, ATI Radeon 3650 graphics,4GB RAM, latest Lenovo drivers installed..
Problem:- Our 2 T500s cannot boot from any windows coded recovery CD -except Lenovo's rescue/recovery discs. Some -but not all- Linux code recovery CDs do boot the T500. Every other kind of CD and DVD such as audio and video works fine in windows XP.
Here an example of our 2 T500s' failure to recognise bootable CD/DVD discs. All the files and folders on a Paragon Partition Mgr v8.5 Recovery CD can be viewed in windows explorer and files such as jpg, txt and zip can be opened. This CD will not boot the T500, however, it will boot our other -non-Lenovo- computers. The same applies when the media are DVDs with identical content.
We have tried several different kinds of CD and DVD media to no avail. Burning the media on other computers and using several kinds of burning software does not help, ourT500s refuse to boot from them too.
The problem seems clear enough, on starup our T500s fail to distinguish between windows coded bootable and ordinary CDs/DVDs -unless they are Lenovo recovery/restore discs.
A solution would be gratefully received.

Thank you for your very kind assistance,
Q: "1. Did you apply the DVD firmware fix here?"
A. It was` already installed on our 2 T500s. We have also applied just about every driver update from Lenovo.
Q: "2. Did you try booting from a USB optical drive that you first attached to another system where you could verify that booting from it was possible?"
A. Yes, many times from a USB CD/DVD drive, it failed too. We burned on that drive too, but the T500s will not boot from those CDs either.
Q: "3. In this thread the solution was to use another burning program than Roxio..".
A. We have used the Paragon internal ISO creator/burner, the Roxio burner that was preinstalled wth the T500, BartPE internal ISO/burner ,InfraRecorder and others too. Made ISOs and burned from them, burned CDs directly on the fly etc, all to no avail..
For some reason, our two T500s' CD/DVD drive controllers or some intermediate software act as if the CD's boot sector is not present. Clearly, something (BIOS, software, unstable hardware, or ? ) is blocking the read or write of the data necessary to boot these CDs. Whatever that 'something' is, it has no effect on burning and booting Lenovo recovery CDs.
The bizarre part of all this is that a`Lenovo recovery CD burned on the T500 drive WILL BOOT the T500. A Paragon v8.5 recovery CD or BartPE CD burned in one of our non-Lenovo computers will boot ithat and every other computer we have except our T500s.
PS Thank you for the link to the new version of Roxio, will download and install it.

Equium will not boot - how to access Recovery partition?

Hi, my sister has a 2008 Equium A200-1V0 with Vista 32-bit which will not boot (probably due to virus rootkit damage). It loads the BIOS but then goes straight to black screen with flashing cursor.
F8 does not work.
F2 goes to Phoenix TrustedCore Setup utility. The Toshiba hard drive and CD-ROM drive are listed in Main and Boot in the correct order.
Using F12 I can get it to boot from a Win7 64-bit repair disc I burned using my laptop.
However, this does not recognise the OS nor any image or restore points (because it is 64-bit) but it will load Command Prompt.
In *Command Prompt*, I can start Notepad and when I click File/ Open and double click on Computer it shows 4 Hard drives as follows:
Local Disk (C:)
Data (D:) 42 GB free of 54.5 GB
WinRE (E:) 1.11 GB free of 1.46 GB
Boot (X:) 29.0 MB free of 31.5 MB (which is used by the Repair disc)
So the C: drive is listed but without capacity.
*CHKDSK*
chkdsk c: /r and press return
"The type of the file system is NTFS.
Unable to determine volume version and state. CHKDSK aborted.
Failed to transfer logged messages to the event log with status 50.
*Running TESTDISK*

1 P Windows RE(store) 0 32 33 191 89 26 3072000
2 * HPFS - NTFS 191 89 27 7477 118 1 117051392
3 P HPFS - NTFS 7477 118 2 14592 190 62 114307072 (data)
* = Primary bootable
When doing Quick Search and then P - list files, of the second partition it reports:
"Can't open filesystem. Filesystem seems damaged."
So what I would like to do is boot up from Windows Restore on the E drive.
My question is to any Toshiba experts: When F8 does not work how do I use the recovery partition???
Laptop is:
Part Number : PSAF5E-002005KS
Key Features
- Intel Pentium Dual-Core Processor T2310
- Genuine Windows Vista Home Premium Edition
- DVD Super Multi (Double Layer) drive
- 2,048 (1,024 + 1,024) MB RAM (667 MHz)
- 15.4 " WXGA TFT display 1,280 x 800

*UPDATE*:
I have borrowed a genuine Windows Vista Home Premium 32-bit dvd and booted up with that.
Clicked on "Repair your Computer"
Then it goes striaght to System recovery Options but no Operating System is shown. Click Next.
Then:
"Choose a Recovery Tool.
Operating system: Unknown on (Unknown) Local Disk"
*Startup Repair*
This takes 1 second.
Root cause found
System volume on disk is corrupt.
*System Restore*
"X - To Perform an offline System Restore, you must specify which Windows installation you would like to restore.

" No valid backup locations could be found.
Windows cannot find a backup on the hard disks or DVDs on this computer. Attach the correct hard disks or insert the last backup DVD and then start the restore process again. "

*Command Prompt*
This is working fine.
CHKSDK C:
The type of file system is NTFS.
Unable to determine volume version and state. CHKDSK aborted.
The HDD is 120 GB and is split by Toshiba into 3 partitions.
C:\ drive (56GB) is bootable with Windows - this is corrupted.
D:\ drive (55 GB) has all Data - fully accessible
E:\ drive is CDROM
F:\ drive (1.46 GB) is the WinRE recovery partition - this is fully accessible.
So my question still remains: can I recover my Toshiba laptop using this recovery partition?
PLEASE NOTE: as mentioned above, pressing F8 during boot has no effect and therefore Safe Mode cannot be accessed.

Intel iMac will not boot past gray screen

Intel iMac will not boot past gray screen
my system:
new (month old) 24" intel imac, 2.8 ghz, 4 gb ram.
running: leopard (upgraded from tiger, which was pre-installed at purchase), installed 10.5.1 update right before this huge problem occurred.
install discs on-hand: two-disc tiget set, single leopard upgrade disc.
what led to this:
i wanted to install windows using bootcamp on a 50 gb partition.
at this point i was running leopard 10.5
i followed all bootcamp instructions, printing out the guide, as well. once i got into the windows setup, i was prompted to choose a partition to install windows. unlike the bootcamp guide, which showed three partitions, one clearly labeled "bootcamp", i saw only one partition. not wanting to risk writing over my mac partition, i quit the setup and rebooted the mac os. after some googling around, i looked for firmware updates (didn't need any), and then software updates. i decided to try updating to 10.5.1.
i then ran through boot camp again, deleting my previous windows partition, creating a new one, and moving forward as before. once again, i was only shown one partition to choose from in the windows setup. i exited the setup again to reboot through the mac os, but this time, i was only given a blank gray screen.
here's what i have tried so far:
booting from a CD, holding down the C or D keys: no response (in fact, i have to restart the computer holding down the mouse button to be able to eject the CD)
booting with option key held down: gray screen
booting with option key held down with external bootable firewire drive attached: the firewire drive appears as a boot icon, and i can click on it within a five second window, but then the screen freezes after that time period, and nothing changes
booting into target mode while attached to another mac: gray screen (no firewire icon, and drive never shows up on other mac)
resetting NVRAM: i'm able to hear the boot chimes, but no difference in performance. gray screen every time
Safe boot: nothing but a gray screen
Verbose mode: gray screen
Single user mode: gray screen
Single user mode with firewire drive attached: occasionally (not every time), i am able to get the white on black terminal to show up. from here, i'm able to run fsck, but it appears to only be checking the firewire drive. i have tried several times to boot from here, and once it took me to a blue screen with movable arrow cursor, but it never went beyond this.
is there anything else left to try before taking it to apple?
any help would be greatly appreciated.
thanks,

I'd call Apple support at this point. You'll need
to put this issue on the record.
Call U.S. iPod and Mac technical support: 1-800-APL-CARE (1-800-275-2273)
The wait may be long for an agent to come on the line
so expect that and have some other stuff to do in the meantime.
If you have the applecare protection plan, I'd ask about "onsite"
service.
I like your work ! Good luck !

Install Disk for Snow Leopard will not boot on an iMac 27in

My Install Disk for Snow Leopard will not boot on my iMac 27in. The Apple Logo is the only thing the user will see. The current OS on the system is 10.6.6. Upon placing the Snow Leopard DVD in the system, the DVD players spins for a few seconds and displays the Apple Logo. Nothing happens after 20 minutes.

Yes, it is ridiculous how it is impossible to install Snow Leopard. I have two Snow Leopard DVDs: one that I purchased for a Macbook soon after it's release (10.6.0), and one that came with my iMac (10.6.4). Both of these boot up my Macbook (running 10.6.7) just fine. My SL 10.6.0 DVD mounts onto my iMac (Lion 10.7.0), but you cannot run the install. I attempted to boot from this DVD and got the infinite white screen and Apple logo, as some have reported above. The other SL 10.6.4 DVD will not even mount in Lion, and will not even show up as a bootable drive when I attempt to select it after holding alt/option on reboot.
I created a bootable external drive from SL 10.6.0, attempted boot, same infinite white screen/apple logo.
I created a bootable external drive from SL 10.6.4 on my macbook. I attempted to boot from this drive, and got the white screen of death, except that this time I actually got the loading symbol underneath the Apple logo. After about a minute of attempting to boot, the Apple logo changed to a circle with a diagonal line through it (the "NO!" sign).
I took my iMac to the genius bar. They inserted SL 10.6.0, which would not boot. Then they determined that my computer had to run 10.6.4 and later. So, they restored an image of SL 10.6.4 onto my partition (not an install from an image, but an image of SL already installed). Hurray! Snow Leopard was successfully shoved onto my iMac!
I then deleted a third partition on my hard drive I did not need anymore, which somehow screwed up my SL partition (even though it said "Will not erase partition SL or Macintosh HD). Now I am back at square one, and I guess I need to take my flippin iMac back to Apple for them to do what I should be able to do.
I like Apple, but sheesh do I hate Lion right now.

My iMac will not boot through Snow Leopard but will boot through Windows OS

My 2010 iMac will not boot in Snow Leopard, only Windows. Have tried reinstalling Snow leopard a few times and works only for a couple of minutes before freezing and doesnt reboot. Windows works perfect. Snow leopard just doesnt want to boot up past the Apple Logo. It was working fine one day and the next day it froze up and was able to reboot back into Snow Leopard but kept freezing. Now it doesnt load at all into Mac OS.
Brian

Possible scenarios:
1: The 10.6.3 SL retail disk is bad, it happens.
2: Your not using the 10.6.3 SL retail disk but one from another machine which doesn't have the drivers for that machine.
3: Your optical drive is funky or some other hardware issues.
4: Your trying to install 10.6 onto a PowerPC based Mac, no can do.
5: Your not using a wired keyboard for boot key commands, have some other hardware conflicts.
Possible solutions.
1: Copy the SL 10.6.3 disk using Disk Utility to another DVD, the error checking may resolve the original disk's issue.
http://www.brokenhomeboy.co.uk/pierow/blog/2011/10/make-a-bootable-backup-snow-l eopard-install-disc/
2: Make a SL bootable USB
http://www.maciverse.com/install-os-x-snow-leopard-from-usb-flash-drive.html
3: Call Apple for a new 10.6.3 disk (and make copies for backup before Apple discontinues selling it)
If your upgrading to 10.6 to get to 10.6.8 to upgrade to 10.7, be warned of this:
1: Your 10.5 software will not work in 10.7, no more Rosetta or PPC based code.
2: Your hardware will not qualify if it's a 32 bit Intel Core Duo, also you may experience slowdowns in performance over 10.6 (10.6 is the fastest OS X version for Intel Macs) in older Intel hardware (I suggest Early 2011 Mac's and later only for Lion)
3: Mountain Lion 10.8 is reportingly coming out this summer and will not run on a lot of older Intel based Mac's because of heftier graphics requirements.
4: 10.6 has the widest range of current avaialble software and drivers for third party hardware.
My advice, stick with 10.6.8 and stay there, buy a new Mountain Lion machine after this summer. Skip Lion completely.

Solaris 10 - system hung, and now will not boot

I have a SunFire V240 with 2 73 SCSI disks running Solaris 10. Only the first disk has been formatted. The box was newly installed last week.
It had 2 zones set up on it and one of them was running a service out of it (called knowledgetree). I came in this morning (monday), and although I could ping the main server and the zone, I could not ssh to the box. I hooked up a console cable to the box, and there was nothing.
I then went to the OK prompt and typed boot.
It said
1} ok boot disk2
Boot device: /pci@1c,600000/scsi@2/disk@0,0:a File and args:
Can't open boot device
{1} ok
I then typed
{1} ok setenv auto-boot? false
auto-boot? = false
{1} ok reset-all
followed by
{1}ok probe-scsi
Target 1
Unit 0 Disk SEAGATE ST373207LSUN72G 045A
If I type the following I get the results below.
{1} ok show-disks
a) /pci@1c,600000/scsi@2,1/disk
b) /pci@1c,600000/scsi@2/disk
c) /pci@1e,600000/ide@d/cdrom
d) /pci@1e,600000/ide@d/disk
q) NO SELECTION
Enter Selection, q to quit: a
/pci@1c,600000/scsi@2,1/disk has been selected.
Type ^Y ( Control-Y ) to insert it in the command line.
e.g. ok nvalias mydev ^Y
for creating devalias mydev for /pci@1c,600000/scsi@2,1/disk
Does anyone have any ideas on what happened, or what I have to do to get the OS to boot again. I am a bit of a nubie when it comes to Solaris .... I am not sure what happened, or why all of the sudden the server will not boot.
Thanks for the help
Peter

Usually you can just do a "boot disk" or "boot disk1"
devalias will show you what actually devices the short alias map too.
It might be a faulty drive bay.
Try pulling it out of one and plugging it into another.
The do the probe-scsi again.
Then put it back into the first to confirm....

Bios recovery - Computer will not boot up

I have a HP Pavilion HPE H8-1145-SC, my bios will not boot.
I was wondering if there are any ways of changing the jumper setting on the motherboard ( IPISB-CH2) to fix this issue if so how do I do it? or are there any other types of recoveries that I can do.
I have searched the forum for answers and tried some such as taking the battery out and putting it back in but it hasn't worked.

You could not get a boot menu when using a boot disk, any messages on the black screen at the bottom? Could you do me a fav and take a pic of that black screen and post it. I think... not sure yet but this can be your memory.
I would ask for you to preform a memory test using memtest86 but if one disk does not boot this may not either. But still worth a try. If you burn a memtest86 disk and reboot see if it boots into the memory, if not the issue is memory most likely. Do you know how many GB of ram you have installed?
Do you feel like you can opening your case and removing memory dimms? If you have a bad one this may stop it from booting. I hope the memtest86 works cause it would detect that. Windows 7 can boot on 2 GB. If you have say 6Gb than each dimm would be 2GB taking out one at a time keeping one in and see if it boots.
http://www.memtest.org/#downiso
In the window about the first list download the zip Iso and burn it to a CD
** Memtest86+ V5.01 (27/09/2013)**
pre-compiled bootable binary (.zip)
If you feel that this would not work I suggest taking your system to a PC repair shop and have them test the memory.

HT1758 Power failure in the middle of a software update and not the computer will not boot up. The computer just has a white screen with a grey apple and just loads non stop.

My iMac will not boot up after a software update. the screen is all whute will show a grey apple in the middle and will look like it is working but nothing happens; this can go on forever.
Does anyone have any suggestions?

Do you have a backup in the form of a bootable clone or Time Machine? Restore that and then try the update again.
Some things to try here (Safe Boot)
http://support.apple.com/kb/TS2570
Another option might be to download the standalone from Apple Downloads on another Mac and try installing it in Firewire Target Disk Mode to the Mac that was interrupted during the update.

Macbook Pro will not boot up / circle with line in it

Mid 2012 MacBook Pro bought brand new
OS X Yosemite
Core i7
16Gb memory (upgraded shortly purchase)
500Gb SATA
About a month ago my laptop started running really slow then locked up, I had to hard power down and every since it will not boot up, all I get is a circle with a line through it.
It will not boot to restore DVD
It will not open safe mode
it will not boot to USB
I have removed the memory (2 x 8gb) and tested one at a time did not help
Removed the HDD and tried to boot to DVD did not help
like I was saying above this all happened at once one min it was good then it locked and I have never got the OS to boot up again

I was going to say try single user Command/ S. but you tried that. You say you tried a dvd. What OS was on it. The 2012 Macbook Pro does not come with a bootable dvd, unless you make one . And it has to be an OS that is the same on newer than the year of the Macbook. Will it start to the recovery partition by Holding the option key or Option/ R at start. Also your machine is suppose to be able to boot to internet recovery using Command/Option/ R. Did you try that. Need to find out if it's the hard drive or something else. Having some kind of USB external boot drive would help. There is also internet hardware diagnostics by holding down Option/D at start up.

My MacBook Core 2 Duo will not boot up. In safe mode I see keychain problems and Mach 1102.

My MacBook Core 2 Duo will not boot up. In safe mode I see keychain problems and Mach 1102 and it keeps circling through the same error. Also the screen is so faint (pressing the F1 and F2 keys don't do anything). I got this from a friend and he didn't have any of the original discs. Any suggestions? From what I've read it's a problem with a recent update. I've never had a Mac so I'm trying to learn and fix it.

I just had an issue like this. I was able to boot up with an external firewire drive, although it was a lot of trouble. I think doing an option boot finally worked; holding down the option key, I eventually got to see the firewire drive was bootable, and booted from it.
I put the thing in verbose boot mode (command - v , I think; but please look it up. I have no Mac books at work to check). In verbose mode, you could see that the hard drive could not mount; the OS tried to do fsck, but it failed around 2/3 of the way, and the CPU was halted.
I was occasionally able to boot normally, but never in safe or single user modes; these do a disk test first, which invariably failed.
I could see from the system and console logs when I managed to get the firewire boot going that there were repeated errors trying to access drive s03, the internal SATA drive. The logs on the SATA drive showed huges numbers of errors. At a wild guess, for some reason a lot of sectors went bad all at once. There had been a some erratic behavior before, but I'd put that down to the single processor G5 problems. (these were non video related, just freezes).
Applecare wanted me to carry the huge thing into the local Apple store, but I persuaded them to just send me a replacment hard drive, which they did. The new one works perfectly.
PowerMac G5 1.8 SP (late 2004), 1.42 mhz 14 iBook Mac OS X (10.4.3) both with 1.5 GB Ram

My powermac dual g5 will not boot up and/or wake up from being asleep

My power mac will not boot up. I hit the power button and it mades the first sound but not the boot sound. My keyboard will not light up or turn on. I replaced the pram battery I hought that might help. It didn't. I am not sure hot to open the disc drive w/o the keyboard working. I am not sure what to do next. I did not hear any clicking from the hard drive. I hope my hard hasn't died. I am running os 10.4.9 Thanks!

If you can get an external 3,5" HDD enclosure, I'd take out the disk(s) that are not backed up, and back them up first on another computer. (You actually should have had bootable backups in the first place, but it's never too late to learn, you learn the hard way ;-)
I could be wrong but I still have a strong feeling that it's a PSU problem.
Good news: if your fans still work, the PSU is not blown (yet). I suspect that dust could cause the symptoms you're seeing.
You have access to an air compressor? Preferably one that has a moist filter. (Canned air is way too expensive, but an option if you don't know anybody with a decent air compressor. Pressure of a can is lower too)
I'd first try to blow it out without disassembly. The PSU is on the bottom, so blow through the frontgrid at the bottom.
You won't be able to get all the dust out, but it might work allready.
I recommend you do this outside, and be surprised by the huge dustcloud that comes out, and be glad you didn't do it in your house.
If that didn't work, I would disassemble your G5, take the PSU out, blow it out more thoroughly, by opening the case of the PSU.
You will find links to guides how to do this in the thread I mentioned in my previous post.

2009 Mac Pro Quad Will Not Boot

Hi.
I have a 2009 Quad 3.0Ghz Mac Pro that will not boot up.
I went to it this morning and the beach ball was spinning. I could not get it to stop and as a last resort, turned it off. It has been working fine, although
I have noticed a little slow (Could be me, though).
When I tried to reboot it, it tried to start, chime went off, but it stayed on the light grey screen and eventually, it had a folder with a question mark in it
that blinked.
I disconnected all peripherals, no change.
Tried to boot from the optical drive with Disk Warrior, no change.
Anybody have any ideas?
Thanks in advance for any help.
Brian

The Chime is generated in Software when the first part of the Power-On Self Test has passed. If an appropriate source of software can be found, booting is likely.
it had a folder with a question mark in it that blinked.
That says it could not find the last-specified source of software. the drive may be damaged, or it may have forgotten where it should be looking.
Tried to boot from the optical drive with Disk Warrior, no change.
Next try a 10.6 DVD. "A Mac that cannot boot from an appropriate Installer/Utilities DVD has a Hardware problem".
One of the simplest things it should be able to do is Startup Manager. Hold down the Alt/Option key at startup and it should draw a gray or blue screen and slowly draw an Icon for each potentially-bootbale device (including a bootable DVD, if inserted).

Satellite Pro A120 will not boot up

Sorry for bad English!
My computer will not boot.
I want to install a BIOS but connecting it to another computer but I dont know how?

In my opinion its not a faulty BIOS but I think the virus on your notebook caused this issue.
The error message says everything:
+Malicious program will access to the read memory+
+problems on bios+
If you are not able to boot up the notebook, neither from the Recovery CD, bootable CD (XP, Linux) nor from HDD then its a serious issue and you should definitely contact the ASP in your country.
If you are a lucky man then the ASP technician would be able to flash the BIOS ROM using a special procedure and the notebook should function again.
Bye

Optical drive trashed and MB Pro will not boot from USB image

Hello,
New here but I have searched and tried all I know to get this MBP working right again. My disk drive is trashed and has been for some time now, this is why I have a bootable version of Snow Leopard on an 8G flash drive. When my MBP began acting funny recently and I went to disk utility to verify permissions and the disk. Both failed = must boot from disk to repair, thus my issue. For some reason by MBP will not boot from the usb image I have used previously??? Pressing C or Option during startup does not work. If I press Option, I only get the harddrive option, C yields nothing and the computer boots normally.
Please!! let me know how / what you would do to resolve this. I don't understand why I have previously been able to boot from this same file on the same drive previously to repair my disk / permissions but cannot do so now. FWIW, I tried placing the file (OSX) on my external HDD to boot from, this did not work either (USB HDD).
Thank you in advance for your input!!

It isn't clear what you mean about your HD being trashed or which disk (HD or USB drive) you are trying to repair, but either way you need to start up from your Snow Leopard installer DVD & instead of installing anything go to the Utilities menu & run Disk Utility from there to repair either or both of the disks.
