Lion Cannot Find Boot Disk

This morning my mac mini was hung when I found it, I could not do anything and it was unresponsive so I power cycled it. Now it posts to Mac OS X Utilities with the following options:
Restore From Time Machine Backup
Reinstall Mac OS X
Get Help Online
Disk Utility
The disk utility option gathers the following information when the application is initialized:
320.07 GB ST9320325ASG Media
disk0s2 (greyed)
SuperDrive (greyed)
disk1
Mac OS X Base System
"disk1" is locked and the SuperDrive is greyed because there's nothing in it. I can use the First Aid utility to verify "320.07 GB ST9320325ASG Media" as well as repair it, but disk0s2 is not mounted for some reason. I believe I need to mount this disk before I can boot from it or use any of the other options to restore my system to functionality, but I don't see how to complete this operation. Can someone kindly point me in the correct direction?

Have you tried clicking on the greyed out disk and seeing if the 'Mount' icon in the taskbar becomes active?

Boot camp, "cannot find installation disk."

What do I do? It's a Microsoft download from the MSDN Academic Alliance (Win 7 Prof. 64-bit) and I am getting this error.
I downloaded the Win 7 Prof. from Microsoft's MSDN AA site on a PC.
Opened boot campo and created the partition and the CD is visible in finder (.ISO) but boot camp says "cannot find installation disk."
So I moved the .ISO to my desktop and burned a new CD using the iMac Superdrive and receive the samer error.
Anyone have any ideas?

Boot Camp will not install from an ISO file. You must have a bootable DVD. Whatever is on your disc image it apparently is not what is on a bootable DVD. You may simply have a .exe installer application that will only work on a Windows machine or on a pre-exisitng Windows system on a Boot Camp partition.

Solaris 10 x86 b72 "Cannot find boot.bin" booting from SCSI.

Hello,
After several gyrations of installation attempts and dealing with early BIOS PnP issues, I've finally managed to get Solaris 10 x86 installed on an old dual P2 333Mhz system. So far the system is running flawlessly, but I'm still not able to boot directly off the SCSI disk. The primary boot handler is erroring out that it cannot find boot.bin.
I can boot fine off of the IDE CD drive and the floppy (currently pointed to autoboot into the SCSI disk as a workaround). But when I try to boot directly off the SCSI drive, I get the error from the Solaris boot manager that it "Cannot find boot.bin".
I have booted off the CD & Floppy and compared the /boot files from both the CD & floppy, but I cannot find any difference that would prevent the primary boot loader from finding boot.bin. I've even compared files to make sure they were not corrupt, and even force re-installed the boot handlers, and manually partioning, always with the same results. I've also tried both enabling and disabling the DOS >1G translation of the Adaptec SCSI BIOS with no change. I can't find any reason that the boot loader is not seeing boot.bin, or that the file is corrupt in any way (even after several wipe and install attempts).
My System is:
Supermicro P6DLS dual Pentium II 333MHz & 512MB RAM, w/ Adaptec 7880 SCSI-UW and IDE (whopping UltraDMA 33) interfaces.
CD/DVD reader is configured as the secondary master (moved from primary master in an attempt to fix boot problem)
HD is a 16GB UW SCSI disk.
(Other particulars ommited unless someone feels they are relevant to the boot process).
The system came to me with Windows 2000 installed and functioning. I also had Fedora Core 3 installed, both with no boot problems of the SCSI disk. (Although FC3 would not see the second processor even with the canned SMP kernel).
This system is intended to replace a Fedora Core 3 system to be a multi-purpose firewall gateway & proxy server and I'm really liking the performance I'm seeing with Solaris 10 on this system but would like it to be able to go through a normal boot process and not have to depend on a floppy as a boot device to get started.
Anyone have any ideas why the Solaris x86 boot loaders think that they cannot find boot.bin when the full /boot partion is intact?
TIA,
-Troy

I'm getting the same problem trying to install
Solaris 10 in VMware from DVD.
It brings up the Solaris Primary Boot Subsystem, so
it appears to be reading fine, but the only thing
that happens is I get the Cannot find boot.bin
error.Hmm, the "Cannot find boot.bin." message comes from the
CD/DVD's boot code, which is contained in the first 16 sectors
of the media.
The boot.bin file is supposed to be read from the Solaris UFS
slice, which starts at 512 byte block #5151360 (or 2048 byte
dvd sector #1287840). This a byte offset of ~2.6 GBytes.
Maybe an issue with your system's bios not being able to read
DVD media > 2GB, during DVD boot?
Or a problem with burning the DVD media? Maybe some
"smart" PC DVD burning software has decided only to record
the 2.6 GB ISO filesystem, and the 100 MB Solaris UFS
filesystem that follows the ISO filesystem is missing on the DVD?
Or a 2GB filesize issue while burning the DVD?
Do you have a pc / windows utility that can print some information
about the S10 DVD media, especially the size of that DVD?
Maybe your CD/DVD recording software?
The original S10 GA x86 DVD image has a size of 2732195840
bytes, or 1334080 2K DVD blocks.

Toshiba/x86 -- Cannot find boot.bin

I am trying to install Solaris 10 on a Toshiba Satellite A10 laptop, I insert CD 1, and it goes to Primary Boot, and then says "cannot find boot.bin". I tried to boot from the other 3 disks, but unsurprisingly, it did not work. I read every posts about "boot.bin" on here, but was not able to find anything that worked.
I looked in my BIOS but there isn't any settings that would change anything.
Thank you.

Hey,I have the same issue.
I got a installation DVD,but it reported "cannot find boot.bin".What can i do now?
I'm waiting for the answer,if you got it,tell me the correct method please.
Thank you for all your help.

Install cd won't boot: "Cannot find booted cdrom device"

I have sucessfully booted linux from CD when using systemrescuecd in order to make my partitions.
In searching I found this post and this one, both of which address similar issues but not exactly the same. The first is the most promising but provides no solutions.
Help would be appreciated.

I get the same error, but a slightly different setup leading to it.
My hda died, so I put a new drive in and I'm trying to install from scratch. Since I had linux on this box already, sda and sdb are a pair of 750G drives that I use in a RAID1 software mirror. So my physical devices are:

sdb: 750G SATA

Obviously I can't copy and paste (this isn't a VM), so there may be some typos in there.
There are a couple things that seem strange to me:
1) [strike]I don't have a 122GB device in the system, why does sda claim 122942 MB?[/strike] That's my 160G PATA drive, interesting
2) Why is sdb listed twice?
3) [strike]Where is my other 750G drive? They're SATA, it's not like I got the jumpers wrong.[/strike] In my haste to install the new drive, I knocked one of the SATA power cables out... far too easy to do, that'd never happen with the older PATA-style power plugs
The unknown partition table on sdb is expected... I'm using the raw device for software RAID, not partitioned.
I'd try the USB flash drive route, but I don't have one and I need to get this server fixed today... for now, I'll try some older Arch CDs.

Syincing error message "Cannot find required disk" - Help!

I have a third gen 4gig nano that I got at Christmas. I added two CD's onto it when I got it. Now, however, I'm having trouble syning anything else - that's all I've been able to put on it are the two CD's even though I've added more into my library. I keep getting the error message "Cannot find required disk". Can anyone help me or tell me what I need to do?
Thanks in advance!

Even though you're not getting a -50, I'd check on the following document. (Your message is one of the possible symptoms of the problem outlined in the document.)

Error message (can't find boot disk) installing win xp on VirtualBox

In trying to install win xp to a VirtualBox vm, I get an error message that a boot disk can't be found. This seems logical to stupid me, as I have not yet installed the win system from the install disk. Instructions that came with the VirtualBox said I must have windows installer on my computer to install win xp. So I downloaded it, but cant figure out how to install it on the vm. To further confuse things, I can't seem to find information as to whether my Intel 2ghz core duo is a 32 bit or 64 bit chip.
Thanks for any help you can give me...
Phil (confused in Menifee) Green

Hi, Dave & Dave -
Wow, that took longer than I thought. I have been back for a couple of hours, and spent that time running the uninstall program, and then going to users/library/VirtualBox and deleting that folder, and its contents. Next I downloaded a fresh copy of VirtualBox from the Sun website, installed it on my computer, then ran the VirtualBox set up (setup the settings) and then clicked on the start icon. After the splash screen, I once again got the same error message. I repeated that routine at least three time, all three times I received the same message.
I then got the bright idea to go into my time machine and went back to several days after I had installed the program previously (March 25, 2009) and retrieved both the program from the application folder, and the vb folder from the user library, restoring them to my present computer state. After all, I thought, if it worked on March 25th, those files should work now. DRAT, I was wrong, Got the same message at the same place in the startup routine.
So, Dave and Dave, after a little more futzing around, I'm now back to the same place I was when I first posted about my problem: My win xp disk will still not mount. ****!!!

Installation cannot find a disk to install on

Hello,
Very short version of the problem:
*Tiger installation does not detect any harddrive to install to*
Full story:
Yesterday I bought my very first iMac. It's a 20" wirh 2Gb ram and 300Gb disk.
It was preinstalled with Tiger. I did the updrade to Leopard mself. No problems there.
Then I treid to install Windows using bootcamp.
Since then, a lot of problems.
The system will not start anymore.
So, since this is a fresh system, I have no problem starting all over again.
I can't directly start with Leopard since they are only upgrade disks, so have to install Tiger first.
When I have the install-1 Tiger disk in the CD and start the system, the upgrade
starts.
*But at a certain point it shows the box with available Harddrives to install to.*
*That box is empty on my screen !!!!*
*This is the problem: The apple cannot find my harddrive anymore.*
does anybody have a clue what to do now?
Thanks in advance for your help.

Cannot find boot record of WD Raptor on KT4

Hello forum, this is my first post.
I have been searching Google for a solution of my problem and found this forum. However, after searching this forum and reading quite a few threads I still could not find the solution. Here's my problem:
I have a brand new WD Raptor 74 GB connected to serial 1 as a single drive. The mainboard is KT4 Ultra BSR. I have built an array by pressing ctrl-f at bootup. The only option was stripe and I have set the array (array 1) as bootable. I went into BIOS and set the array as first in boot order. Conclusion, the BIOS seems to detect my array and so far so good.
I booted Win XP installation CD and pressed F6 to install the Promise drivers. I used the newest drivers which were downloaded from MSI yesterday. Installation detected my array so I created a new partition, formatted it and the installation program copied files to that partition. When copying was finished, the computer had to be restarted and it was supposed to boot from my harddrive where it copied the files. Now to the point of my problem: BIOS has detected my array and tried to boot, but it says that boot record could not be found! I don't know whether Windows installation has failed to create a boot record or BIOS could not detect the boot record.
I have checked the contents of C: by booting Win XP installation CD and gone into recovery mode. I would access C: and found the common files used for Windows bootup: boot.ini, ntldr, etc.
So the required files are in place, but either the boot record does not exist or BIOS cannot find it. I wonder if anyone could give me any suggestion about how to solve this problem. I want to make my SATA drive bootable.
Thanks in advance

I have a DVD and DVD-RW connected to IDE2. I had a Hitachi HDD connected to IDE1, but it was removed before I ran Windows installation. The reason is because I want my SATA drive to have C: while having a HDD connected would mean the partions on that drive would occupy the C and D partition letters. I planned to attach the Hitachi after Windows installation has completed. BIOS has no problem detected my array, but when trying to boot from the array, the boot record cannot be found eventhough I have run the Windows installation which I thought would create the MBR automatically.
Is there any way to make my array bootable? It has been boot-enabled in the SATA settings.

ASMCA cannot find candidate disks

hi gurus
I installed 11gR2 clusterware software on Redhat Linux 4.7 I cannot see any disks in the "Create Disk Group" window when I run ASMCA. I changed the "disk discovery path' to '/dev/raw/* from default,but still nothing was find.
*[root@maoxl etc]# ls -l /dev/raw*
*total 0*
*crw-rw---- 1 oracle oinstall 162, 1 May 16 12:29 raw1*
*crw-rw---- 1 oracle oinstall 162, 2 May 16 12:29 raw2*
I have checked the read write permission on the disks(raw1,raw2 here),it's ok,why ASMCA cannot find them?
Thanks very much!

If you read this you closely, you will find:
a.) Using /dev/raw is not needed anymore, you can directly use the block devices (e.g. /dev/sd*).
b.) Your user right should be grid:asmadmin (or at leas oracle:asmadmin) and not oracle:oinstall.

Replaced Drive and had 10.4 OS on it cannot find original disks

I need to get an installation OS copy for and intel black macbook serial W8730496YA4. The disk went out and I just replaced it but I cannot find my original installation disks and the guy at the apple store said that they don't even have copies that old. I don't want to pay over 100 i just want the OS so my mac will work.... Help

If you don't have your install disks you can get the 10.4 gray disks by calling Apple Store Customer Service at 1-800-676-2775 They can send them to you for about $16 per disk plus S & H. Just give them your serial number and they'll know which ones you need.
Or you can get the Snow Leopard retail installation disk for $29 if you have at least 1gb of RAM and a working DVD drive. http://store.apple.com/us/product/MC573Z/A?mco=MTY3ODQ5OTY You won't need the box set unless you want both the full iLife '11 and iWork '09. If you only want iPhoto or other single apps you can get them from the App Store after you've upgraded to 10.6.6. iPhoto, iMovie or Garage Band for $15 each and Pages, Keynote or Numbers for $20 each.

Cannot find install disk

I just moved and cannot find my install disk. Got a "Volume needs to be repaired" message while doing some maintenance. Is there anyway to correct this without the install disk? If not, how do I get another one without coughing up the dough?

Hi habsolutely, Welcome to Apple's Users Help Users Forums.
Other threads say *call Apple w your serial number*. There is a charge, much less than new system.
Good Luck, JP
