Help: Boot from Tiger partition

Some odd issues on PowerMac Quad running 10.5.1. Any help/advice gratefully received.
Two partitions on the primary drive: Alpha and Tiger-Boot. Alpha is the first partition and is the Leopard boot partition. Tiger-Boot is the second partition - 90Gb - and was cloned from the original Tiger 10.4.11 boot partition before Leopard.
1. SysPref. Startup drives listed as Alpha 10.5.1 and Tiger-Boot 10.4.11.
Choosing Tiger-Boot and restarting doesn't boot from Tiger-Boot but reverts to Alpha. ???
2. Startup holding down <Option> key. Internal Alpha and Tiger-Boot listed but Tiger-Boot cannot be chosen.
3. Startup holding down <Option> key. Internal Alpha and Tiger-Boot listed but not the external drive .... PowerMac refuses to recognize drive as a boot drive but an Intel Mac does. Test was using so this may be the issue here.
4. Decided to reboot from the Tiger Install DVD. Kernel Panic on the gray Apple logo screen just before the rotating spokes logo appears. Completely reproducible even after reseting PRAM (have to go into open Firmware to eject the DVD).
Any thoughts before I spend time on telephone w/Apple?
Thank you.

"...PowerMac refuses to recognize drive as a boot drive but an Intel Mac does..."
USB drive? PPC Macs cannot boot from USB drives regardless of the OS. Also, if the partition "scheme" is not correct, you might not be able to boot any Mac. A PPC Mac needs an "APM" partition and an Intel Mac needs a "GUID" partition. AFAIK, you cannot have both on the same drive.

Booting from a partitioned drive

I have 1,5 TB drive and want to create 2 partitions. One for cloning using Super Duper and second back up by data files. Is this possible? Because I read that Apple doesn't officially support booting from Apple partition map on Intel Macs and doesn't allow to install the OS X.
Thanks,

Well, after using disc utility, I had a bad luck... kernel panic during the partition. And the computer panics anytime the drive is plugged in. Firewire and USB. I tried my other computer .... the same thing. That means the drive is dead!
Oh Well...
Here is the error:

Can't boot from Ubuntu partition after upgrading to Yosemite

When i go to Disk Utility the Ubuntu partition appears as it always have, i had installed since Mavericks refind to boot from any partition. Now refind doesn't work and the alt/option key doesn't work either. Does anyone know a way to fix this?

A extensive report already written is in the Ubuntu stacks as
Dual boot Linux and Yosemite
Basically you need to follow http://www.rodsbooks.com/refind/yosemite.html
wherein it explains that Yosemite is using a new LVM bootup from within the Recovery Partitions 10.10.
This messes up REFIT/REFIND tools which have previously installed Partition 1.S
See my current Table below , wherein << are my comments
Current GPT partition table:
#      Start LBA      End LBA Type
1             40       409639 EFI System (FAT)    << old preferred site for REFIT/REFIND tools
2         409640    154061023 Mac OS X HFS+ << main Mac partition
3      154061024    155330559 Mac OS X Boot << Recovery 10.10 , installed by Yosemite update, used to start MAC boot. BUT is not shown by Disk Utility, to prevent its naive deletion which would kill the MAC boot.
4      155330560    156598271 Mac OS X HFS+ << old Recovery 10.9, simply retained
5      157869786    228772129 Unknown << My Ubuntu partition
6      228772130    236765969 Linux Swap << which was shortened by 200 MB to make room for 7)
7      236765970    236974814 Mac OS X HFS+ << installation site of REFIND. Though 4) could have been used, there is a possibility that Apple might have future plans for this small 4) partition.
With 7) created (see detail below), my REFIND install command under MAC, within Downloads/refind-bin-0.8.3/ was:
sudo ./install.sh --alldrivers --ownhfs /dev/disk0s7
There was still required the edit if refind.conf.sample specified in Yosemite.html, which I named refind.conf.edit1
This was copied with:
sudo cp refind.conf.edit1 /Volumes/macefi/System/Library/CoreServices/refind.conf
macefi is my name for the MAC /dev/disk0s7 mount point, equivalent to /dev/sda7 under Linux
CAREFULLY do read Yosemite.html, as the instructions here are too terse by themselves!!!!
There are 2 routes to boot Ubuntu, and then creat 7) with GPARTED
a) If you can access the GRUB shell under an old REFIT/REFIND installation, partitions will be shown by:
grub> ls
Presence of a Linux file system can be confirmed by a command like:
grub> ls (hd0,gpt5)/
Output of
grub > ls (hd0,gpt5)/boot/grub/
should include a grub.cfg file. Then you can boot as usual with
grub > configfile (hd0,gpt5)/boot/grub/grub.cfg
After boot up, start GPARTED
b) Alternatively boot with the Ubuntu install disk, and choose the Demo option
Open a text console, and get admin proviledge with:
$ sudo su
# gparted
Using GPARTED, unmount if necessary any terminal SWAP partition, such as my 6) above
Then shrink the SWAP partition end by a trivial 200 MB,
Create a HFS+ partition in like my 7) for a coming REFIND installation
Note, that a file /etc/fstab contains a SWAP partition specification, which should be edited for automated SWAP start.
# sudo blkid /dev/sda7
will report the SWAP space specs LONG uuid code. This can be copied into memory by dragging the mouse over the uuid
Then SHIFT-CONTROL-C will copy it into memory.   Start an edit with:
$ sudo nano /etc/fstab
delete the old swap uuid, and paste in the replacement with
SHIFT-CONTROl-V
and swap should mount upon reboot, or with:
$ sudo swapon -a
Check with:
$ free
which should report none-zero swap space.

[SOLVED] UEFI system booting from MBR partition table and GRUB legacy

I'm trying to understand once and for all the process by which Arch can be booted from a system with UEFI firmware and an MBR partition table. Some of the information on the wiki seems conflictual / non-nonsensical at times. Apologies in advance if this has been answered time and time again, but I did search around and all I found was fixes to get Arch to boot rather than comprehensive explanations of the boot process.
Now, the way I would imagine it works is that it's just completely identical to the way it would work with a BIOS firmware. The UEFI firmware detects an MBR partitioning scheme (or is configured to know it's an MBR partitioning scheme), activates some "legacy" mode and executes the MBR boot code, just like a BIOS firmware would.
The wiki however, says different. From the Macbook article: "Do not install GRUB onto /dev/sda !!! Doing so is likely to lead to an unstable post-environment."?
So what is there in the MBR boot sector? Nothing?
How does the firmware know what to boot if there's no 0xEF BIOS boot partition and no Grub stage 1 in the MBR boot sector?
Also, how does installing Grub stage 1 to a partition work? Does it have to be at the beginning of the partition? Wouldn't that overwrite some existing data?
I'm especially puzzled since many guides to installing Vista on a macbook recommend simply formatting as MBR, and installing as normal, which I suppose entails having the Windows installation process write its boot code to the MBR, ie the equivalent of installing grub stage 1 to /dev/sda rather than to the /boot partition, as the Macbook article suggests.
Any input is appreciated.
P.S. I realize it's probably simpler, if I just want to dual boot Windows and Arch, to install Windows 7 in UEFI-GPT mode, let it create the EFI System Partition, and then install GRUB 2 to that partition, but I'm still curious about the UEFI-MBR boot process.

CSM in UEFI firmwares do the exact same job as normal BIOS firmware.
So it's something specific to the Mac that it's able to boot from a partition's VBR while ignoring the MBR?
The reason that warning is given is because grub-legacy modifies more than just the MBR boot code region. It can overwrite some parts of GPT header.
Not true, the instruction is given in the context of an MBR format, not in the context of a GPT format, so there's nothing to overwrite and Stage 1.5 should be safely embeddable in the post-MBR gap.
In BIOS boot (normal case in non-UEFI firmwares or CSM in UEFI firmwares) does not read the partitition table (atleast it is supposed to be dumb in this regard), it simply launches whatever boot code exists in the 1st 440-byte of the MBR region.
So again, you're saying it's specific to the Mac UEFI that it lets you choose a partition whose VBR to load, regardless of what's in the MBR?
I haven't used Macs so I can't comment on Mac firmware behaviour. But normal BIOS firmwares (legacy and CSM) launch only the MBR boot code and not the partition boot code. We need some chainload capable boot manager in the MBR to launch the partition VBR.
grub-legacy does not know anything about GPT. So when you install grub-legacy to /dev/sda, it install the MBR boot code (stage1) and stage 1.5 code to the (supposed) post MBR gap. Since there is no actual post MBR gap in GPT (which has been taken over by the header and partition table), grub-legacy does not check for GPT and it assumes the post MBR gap actually exists which is invalid in case of GPT. grub-legacy embeds the stage 1.5 code in GPT header and table region (which grub assumes to be unused post MBR gap) and thus corrupts it.
0xEF is the MBR type code for UEFISYS partition. grub stage 1 (used in grub-legacy, not in grub2) is the 440-byte boot code stored in MBR for use in BIOS boot.
That's precisely my point: with neither proper executable code in the MBR (since grub was installed to a partition, not to the MBR) nor a UEFI system partition, what does the firmware default to, and how does it know what partition to boot from?
In that case it might fallback to UEFI Shell (if it exists) or give an error similar to the case where BIOS does not find any bootable code in 440-byte MBR region.
So even with bootcamp/CSM, the disk also needs to be MBR partitioned. So Macs use something called "Hybrid GPT/MBR" ( http://rodsbooks.com/gdisk/hybrid.html ) where the MBR table is synced to match the first 3 partitions in the GPT table.
I know what Bootcamp does, and that's not what I was referring to. I was referring to standalone Vista installs. I wasn't puzzled at the fact that they were using MBR, I was puzzled at the fact that contrary to the recommendations for the standalone Arch install on the wiki (with MBR partitioning, not GPT), they didn't do anything to try and prevent Windows from writing to the MBR.
You can't prevent Windows from overwriting the MBR region. You have to re-install the bootloader (grub2/syslinux etc.) after installing Windows. That is the reason why it is recommended to install Windows first and linux later.
Thats not true. I actually find it is much easier to install Windows UEFI-GPT using USB rather than a DVD.
I haven't done it since the only UEFI system I own has no DVD drive, but I was under the impression that it was simply a matter of choosing DVD UEFI boot in the firmware's boot menu.
format the USB as FAT32 and extract the iso to it. That it.
No, thats not it, precisely, it doesn't work out of the box with a standard Windows install USB, you need to fiddle around:
2.3 Extract bootmgfw.efi from [WINDOWS_x86_64_ISO]/sources/install.wim => [INSTALL.WIM]/1/Windows/Boot/EFI/bootmgfw.efi (using 7-zip aka p7zip for both the files), or copy it from C:\Windows\Boot\EFI\bootmgfw.efi from a working Windows x86_64 installation.
2.4 Copy the extracted bootmgfw.efi file to [MOUNTPOINT]/efi/microsoft/boot/bootmgfw.efi .
Most of the Windows isos already have /EFI/BOOT/BOOTX64.EFI file, so no need to extract the bootmgfw.efi file.
There is no difference between in BIOS booting in UEFI firmwares and BIOS booting with legacy firmware.
There has to be a difference, at least in the Mac firmware (sorry, I keep switching), since legacy firmware, AFAIK, cannot chainload a bootloader in a partition's VBR without there being some sort of "stage1" code in the MBR.
No idea about Mac EFI. Apple made a spagetti out of UEFI Spec. To actually understand how Mac firmwares work, read the blog posts by Matthew Garrett of Redhat, about his efforts in getting Fedora to boot in Macs.

Boot from 2nd partition on mini

I have a new mac mini with os x server on it. It has two partitions and I tried to install mac os x onto the other partition so I could boot from that. I have an apple external dvd drive attached to the mini.
Everything went well, it allowed me to install to the partition I wanted. Then when it does a reboot it will not boot with the mac os x disk in the dvd drive and if I take it out it boots back to mac os x server partition. If I hold down the Option Key at the start it does not show me the partition with the os x on it.
Using finder I can see a bunch of pkg files in a folder called Mac OS X install Data on the partition I want to use. Is there a way of getting these to install?
Sorry if this is a dumb question but I am fairly new to macs.
Thanks.

That's normal behavior. The Recovery HD only has enough code to go to Apple's servers and DL the installer; whereas, the InstallESD contains everything. Do note, however, that running either will check Apple's servers for additional components, whatever those might be. Thus, Internet access is required to do either.

Boot from second partition on usb hard drive

I have a time machine external usb drive. I have created a second partition of 8GB on this drive and restored OS X Install ESD 10.7.5 to this second partition so that I can easily rebuild if necessary. I would like to be able to boot from this second partition. When I hold down Option key at startup, I see the external drive as an option, but the iMac wants to boot from the Time Machine Backup partition, rather than the Lion Partition. It doesn't give me the choice of the second, bootable partition on this drive. Is it possible to do this?

Help - upgrading from Tiger to Snow Leopard AND new larger hard drive, MBP

Howdy!
My iPhone has finally demanded that I upgrade my MBP from Tiger. And as if by coincidence, my now puny 100GB internal drive is packed full with less than a gig free most of the time. (10% free is the MINIMUM free allowance, I know!!) I run old copies of Adobe CS2, Quark, Quickbooks, Microsoft Office... would love to keep them working without purchasing upgrades, but probably isn't a realistic hope. None of it is mission critical at this point.
So I've purchased the $29 Snow Leopard DVD (from a reseller - it says CPU Drop-In DVD Version 10.6 on the disk), and a new 750GB internal drive (same reseller - The drive is a 2.5" SATA 5400RPM 8MB-Buffer Hard Drive (9MM Slim) (RoHS Green Friendly)), to get with the times.
My other resources include:
- two 1TB LaCie external drives with FW and USB2 ports
- one other LaCie external drive - I think 360GB?
- Retrospect 5.0 (most of my backups are encrypted Retrospect files on those three LaCie external drives, but there's some room on them)
- a $22 USB 2.0 to SATA/IDE adapter with AC power, to access whatever laptop drive might be without an enclosure temporarily
- a copy of Carbon Copy Cloner software
- I just ordered an upgrade to my ancient (OS9) copy of DiskWarrior
- A monster UPS battery backup and line conditioner that everything plugs into for this process
It has been a long time since I've DIY'd any undertaking this complex, and I'm looking for advice on what to do first, how to go about this.
Here's my setup:
Model Name: MacBook Pro 15"
Model Identifier: MacBookPro1,1
Processor Name: Intel Core Duo
Processor Speed: 2.16 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache (per processor): 2 MB
Memory: 2 GB
Bus Speed: 667 MHz
Boot ROM Version: MBP11.0055.B08
SMC Version: 1.2f10
I'm guessing I should do it like this, PLEASE EDIT or make suggestions or tell me what I forgot to do before I do it!!
1. Back up everything to at least two external locations! Also, make a bootable copy of my current internal drive in its own volume, to at least one external drive that is formatted in HFS+ GUID partition style, with Carbon Copy Cloner (would Retrospect work well for this instead?).
2. Free up at least 20GB on the current internal drive (100GB). Hopefully 30GB.
3. Run Disk Utility on the current internal drive. Fix any problems. (Should I hit it with DiskWarrior instead?)
4. Format the new 750GB drive to HFS+, GUID partitions. (How long will that take? Can I do it with the USB-SATA cable adapter, sitting on my desk, or does it have to be in an enclosure? The adapter has AC power)
5. Run Disk Utility (or DiskWarrior?) on the new internal drive in its temporarily external position. Fix any problems.
6. Boot off the Snow Leopard CPU Drop-In DVD and install onto both drives. (Will this version of the DVD I have wipe all files when it installs to a disk???)
7. See how they run. Boot off the old 100GB internal drive, boot off the new to-be-internal 750GB drive. Panic if it's not going well.
8. If the current internal 100GB drive is rocking Snow Leopard and my familiar files and apps seem somewhat functional, use Carbon Copy Cloner to recreate the volume on the new larger drive. Then swap the drives physically. (Links to good step-by-step instructions on this part would be much appreciated here!!)
9. If the Snow Leopard DVD overwrote or snuffed out my familiar files and apps on the old internal drive, sigh deeply, then swap the drives physically. Use CCC (or Retrospect? or Migration Assistant?) to fetch my junk from the old internal drive's backup and plunk it on the new bigger internal drive (now installed).
10. See how it runs. Shake my fist at the sky over the planned obsolescence of technology paired with the seductive power of my iPhone. Grumpily upgrade the software that I actually create income with.
Please help! I am just faking it here based on a few message boards I've read. Will this actually work properly?
Thanks!

Howdy slowpoke43, and a warm welcome to the forums!
Please help! I am just faking it here based on a few message boards I've read. Will this actually work properly?
LOL, if your faking it you're the best!
1. Yes, absolutely... no CCC would be best in my experience/opinion.
2. Yes, the more he better... Free Space is no longer our Free Space, but OSX's.
3. Indeed, & if you have the correct version of DW, do that.
4. Yes, not long, A/C power is great.

6. Yes, boot off the 10.6 DVD, & no Snow Leopard does by default what we used to call an Archive & Install, saves & updates all your info, APPs, Music, etc., it may quarantine a few things or not but will tell you.
7. Absolutely, but Panic won't be needed with your great preparation & Bootable Backups!
8. Not quite sure I understand, but run SL for a few days before you do anything.
9. Yeah, but again with you doing everything right from the gitgo, I can't picture that happening.
10. Yes indeed, the hangup with yours is that it only holds 2GB of RAM... a pain in 10.5 & up IME.
Again let me say... GONGRATS, I've never ever seen anybody so well prepared & informed despite your diffidence!

Kernel panic when booting from Tiger install DVD

Short version: When I try to boot up from the Tiger installation DVD, my Power Mac G5 gives me a kernel panic. Can anyone help?
Here's the story:
I have a Power Mac G5 that I've been running Leopard on for quite some time now. Unfortunately, the software I need to use (Final Cut Studio 1) has some incompatibilities with Leopard, so I was thinking I would put Tiger back on the machine in a separate partition on the second hard drive.
I tried booting the Power Mac using the retail (black label) Tiger DVD and holding down the "C" key. The Apple logo appears on screen, but is immediately followed by a kernel panic. I'm never able to access the features on the disc. The same thing happens if I try holding down "option" during boot instead: I'm correctly allowed to choose whether to boot from the hard drive or the DVD, but once I choose the DVD, I get the Apple logo and then a kernel panic.
The same Tiger DVD works fine on other computers, so I know it's not the disc. And the Power Mac itself handles everything else without problem.
I'm kind of desperate, as I need to finish this project this week. Any help you could give would be greatly appreciated!

Can I boot from tiger install disk without wiping my hard drive?

I have an old mac install disk with tiger on it and I want to be able to boot from it. Can I do that without damaging my hard drive?

You can boot from it, but if you continue through without stopping eventually it will try to install Tiger. However, if you want to install Tiger on a USB flash drive or HDD, then when you arrive at the screen for selecting a Target device, be sure to select the USB device before clicking on the Install button.
If the USB device has not been properly partitioned and formatted already, then be sure you do this:
Clean Install of OS X
     1. Boot the computer using the Tiger Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the USB drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
If you wish you can download any updates using Software Update preference panel.

Cannot boot from Tiger retail DVD on my G3 iMac

I just got a G3 iMAC 500MHz DV SE slot loading, it has 256+512 MB of Memory and 60 GB Hard disk. Firmware is 4.1.9
When I first got the machine it didn't have an OS so I loaded Tiger on it, with no problems. after a couple of restarts I started getting Kernel Panic right at power up. First it was every now and then but it became consistent later.
So as a solution I thought maybe zapping the PRAM would help (That was a mistake). After Zapping the PRAM I could not load into Tiger at all not from the retail DVD nor the Tiger installed on the HDD. What happens: the computer starts to load you can hear the DVD working it goes into the grey screen with the spinning gear and then eventually the greay apple is replaced with a circle and line across it.
I tried everything, resetting the PMU, zapping the PRAM again, replacing the battery to no avail.
So finally I installed OS 9.2 back, and that was vey smooth, I erased the HDD and did a clean install of OS 9.2, did the update to 9.2.2. Then I tried again with the Tiger DVD, same thing it starts to boot from it and then it stops at the same place.
What is driving me nuts is that I installed Tiger on the same machine from the same DVD 3 days ago, it only stopped working after I zapped the PRAM. What the heck!!!
Any advice would be appreciated, right now I am running 9.2.2 on it no problems...
Thanks..

Since your firmware is up to date, your problem is probably bad RAM. Often RAM that works fine with OS 9 will cause problems with OSX. Try with just the original Apple RAM (it will be slow, but OSX should still run). If it works, you may be able to test one of those lifetime RAM warrantees.
Have you run the Extended test from the Apple Hardware Test disk? It doesn't find all errors, but if it says something is bad, believe it.

Kernal panic when booting from tiger disk

My friend just called me with a computer issue. She just got a used computer and it had a password setup. i told her how you can boot from the tiger install disk and reset it. She put the disk in and started holding down C before she turned it on. It sits there and thinks for a while and then she gets a kernal panic with the prohibitory sign before it gets anywhere (to the install screen). I have no idea what to tell her and she's 3 hours away so I can't really go over there easily.
Could the fact that she started holding down C before she turned it on make a difference?
Any help is appreciated.

The correct procedure for booting from the DVD is:
Start the computer and immediately after hearing the chime press and hold down the "C" key with one hand while inserting the DVD into the optical drive quickly with the other. Continue holding the "C" key down until the computer starts up from the DVD.
If the computer is already turned on, then insert the DVD into the optical drive. Restart the computer and immediately after the chime press and hold down the "C" key until the computer starts up from the DVD.
If the computer continues to panic despite the above procedure, then there's likely a major hardware problem.

Help booting from external hdd

So I ran disk utility on my internal HDD and received a message telling me to back up as much info and reformat. I purchased a 3TB WD My Studio external and CCC. I followed the instructions via CCC to format and create the recovery partition afterwhich I cloned my internal HDD. When I go to boot from the external, holding the option key down, I first get a message to connect wireless keyboard followed by Disk Utility activation. After quiting Disk Utility I'm promted to select startup disk which I selected the WD Mybook drive followed by restart. After restart nothing except a light grey screen. Any help is greatly appreciated! Thanks in advance.

Anyway, I don't use TM as I don't care for it. I use bootable clones - I have two of every system I'm running. However, I also still want the recovery partition. And, when I upgraded my MBP to an SSD, I installed the "ex" internal drive in the external enclosure for an instant backup copy.
Yeah, the board is messed up tonight lots of posts you cant see.
I just posted this 2 days ago on this topic...., see what you think:

I dont care for TM either, same reason DS store doesnt. Also there are no Pros using TM as an archive or storage utility.
Agreed, but if you have this >

Then you youve got a recovery partition.

However, I also still want the recovery partition.
But WHY?? If youve got clones like myself, what use for a recovery partition? ...I Dont need it, never will.

Can't boot from recovery partition in Mountain Lion

I've installed Mountain Lion on two different boxes so far: a 20" iMac at home and a Mac Mini at work. Both had up to date Lion installations prior to the upgrade. After installing Mountain Lion I am not able to boot in to the recovery partition on either one. Whether I hold down Command-R to go directly to the recovery parittion, or simply hold down Option to get a choice of boot devices, I am taken directly to the login screen.
The recovery partition is there on both boxes, and I can mount it and examine it using 'diskutil' from the command line. I created a USB image of the recovery partition on the iMac, and the Startup Disk control panel allowed be to select it as a boot device, but the box (both boxes, actually; I also tried it on the Mini) booted directly to the login screen.
I honestly don't know whether I could boot to the recovery partition prior to upgrading to Mountatin Lion or not. When I first installed Lion on the iMac I did not get a recovery paritition, but Apple sent me a USB drive and after cleaning up the disk (getting rid of an unused Boot Camp partition) I was able to get a clean install with a functioning recovery paritition. However I never booted from it after confirming that it worked.
Anyone else see anything like this? Or have an idea how to fix it?

Ok but you can get the Option key to work.
There is a utility to Rebuild the recovery HD partition.
Look here first.
Removing and rebuilding a malfunctioning Recovery HD partition « Der Flounder
Then in that article a link to download or find the Recovery HD utility on the Apple website.
But that was originally for Lion. So you may have to rebuild the Lion R-HD then Reinstall Mt Lion over the top of your current install of Mt Lion for it to make the Mt Lion R-HD.
Depending on the age of your Mac's you may also be able to use the Online (Internet) Recovery HD system. To get to that with a R-HD partition on the system, even if that R-HD partition sin't working, you hold down Command+Option+r keys when starting the system (And yes with the USB keyboard attached).

hi Moh27,
Thanks for Using Lenovo community Forums!
Inside BIOS under boot tab you will find there UEFI Boot you will need to disable that
then u need to move the USB HDD: GENERIC USB HDD to number 1.
You can do that by highlighting the USB HDD: GENERIC USB HDD and pressing F5 or F6 to move it up
-or-
Highlight the things on top of the USB HDD: GENERIC USB HDD then put them down still using the F5 or F6 to move them down, do it one by one till the USB HDD is on top.
Just make once you got the USB HDD: GENERIC USB HDD to 1 hit F10 to save and exit changes.
Hope this helps,

Blue & White G3 won't boot from Tiger DVD

Correct me if I'm wrong, but the B & W G3's ARE supported under OS X 10.4 right? This computer came to me only a week ago with 10.3.9 installed (flaky, but working), 32x CD-ROM, 384 MB RAM, 25 GB HD. The PRAM battery is dead. I was also given an NEC 5x DVD-ROM to install. This works fine (when it wants to) when booting with an OS 9.2.2 CD-ROM, and it can see and open the Tiger install CD... but it will NOT boot from it for some reason, computer just sits and idles. Any ideas?

This article concerns a specific problem with the Blue & White G3 and the Matsushita CR-587 CD-ROM drive. However, it shows an Open Firmware workaround that you could try:
25793- Power Macintosh G3 (Blue and White): Unable to start from Mac OS X 10.3.2 Install CD by holding "C" key
