CLUSTERING WITH ZFS BOOT DISK

hi guys,
i'm looking for create a new cluster on two standalone server
the two server boot with a rpool zfs, and i don't know if in installation procedure the boot disk was layered with a dedicated slice for global device.
Is possible to install SunCluster with a rpool boot zfs disk?
What do i have to do?
Alessio

Hi!
I am have 10 node Sun Cluster.
All nodes have zfs rpool with mirror.
is better create mirror zfs disk boot after installation of Sun Cluster or not?I create zfs mirror when install Solaris 10 OS.
But I don't see any problems to do this after installation of Sun Cluster or Solaris 10.
P.S. And you may use UFS global with ZFS root.

How to back up a ZFS boot disk ?

Hello all,
I have just installed Solaris 10 update 6 (10/08) on a Sparc machine (an Ultra 45 workstation) using ZFS for the boot disk.
Now I want to port a custom UFS boot disk backup script to ZFS.
Basically, this script copies the boot disk to a secondary disk and makes the secondary disk bootable.
With UFS, I had to play with the vfstab a bit to allow booting off the secondary disk, but this is not necessary with ZFS.
How can I perform such a backup of my ZFS boot disk ?
I tried the following (source disk: c1t0d0, target disk: c1t1d0):
# zfs list
NAME USED AVAIL REFER MOUNTPOINT
rpool 110G 118G 94K /rpool
rpool/ROOT 4.58G 118G 18K legacy
rpool/ROOT/root 4.58G 25.4G 4.50G /
rpool/ROOT/root/var 79.2M 4.92G 79.2M /var
rpool/dump 16.0G 118G 16.0G -
rpool/export 73.3G 63.7G 73.3G /export
rpool/homelocal 21.9M 20.0G 21.9M /homelocal
rpool/swap 16G 134G 16K -
# zfs snapshot -r rpool@today
# zpool create -f -R /mnt rbackup c1t1d0
# zfs send -R rpool@today | zfs receive -F -d rbackup               <- This one fails (see below)
# installboot /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c1t1d0s0
The send/receive command fails after transfering the "/" filesystem (4.5 GB) with the following error message:
cannot mount '/mnt': directory is not empty
There may be some kind of unwanted recursion here (trying to back up the backup or something) but I cannot figure it out.
I tried a workaround: creating the mount point outside the snapshot:
zfs snapshot -r rpool@today
mkdir /var/tmp/mnt
zpool create -f -R /var/tmp/mnt rbackup c1t1d0
zfs send -R rpool@today | zfs receive -F -d rbackup
But it still fails, this time with mounting "/var/tmp/mnt".
So how does one back up the ZFS boot disk to a secondary disk in a live environment ?

OK, this post requires some clarification.
First, thanks to robert.cohen and rogerfujii for giving some elements.
The objective is to make a backup of the boot disk on another disk of the same machine. The backup must be bootable just like the original disk.
The reason for doing this instead of (or, even better, in addition to) mirroring the boot disk is to be able to quickly recover a stable operating system in case anything gets corrupted on the boot disk. Corruption includes hardware failures, but also any software corruption which could be caused by a virus, an attacker or an operator mistake (rm -rf ...).
After doing lots of experiments, I found two potential solutions to this need.
Solution 1 looks like what rogerfujii suggested, albeit with a few practical additions.
It consists in using ZFS mirroring and breaking up the mirror after resilvering:
     - Configure the backup disk as a mirror of the boot disk :
     zpool attach -f rpool <boot disk>s0 <backup disk>s0
     - Copy the boot block to the backup disk:
     installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/<backup disk>s0
     - Monitor the mirror resilvering:
     zpool status rpool
     - Wait until the "action" field disappears (this can be scripted).
     - Prevent any further resilvering:
     zpool offline rpool <backup disk>s0
     Note: this step is mandatory because detaching the disk without offlining it first results in a non bootable backup disk.
     - Detach the backup disk from the mirror:
     zpool detach rpool <backup disk>s0
     POST-OPERATIONS:
     After booting on the backup disk, assuming the main boot disk is unreachable:
     - Log in as super-user.
     - Detach the main boot disk from the mirror
     zpool detach rpool <boot disk>s0
This solution has many advantages, including simplicity and using no dirty tricks. However, it has two major drawbacks:
- When booting on the backup disk, if the main boot disk is online, it will be resilvered with the old data.
- There is no easy way to access the backup disk data without rebooting.
So if you accidentally lose one file on the boot disk, you cannot easily recover it from the backup.
This is because the pool name is the same on both disks, therefore effectively preventing any pool import.
Here is now solution 2, which I favor.
It is more complex and dependent on the disk layout and ZFS implementation changes, but overall offers more flexibility.
It may need some additions if there are other disks than the boot disk with ZFS pools (I have not tested that case yet).
***** HOW TO BACKUP A ZFS BOOT DISK TO ANOTHER DISK *****
1. Backup disk partitioning
- Clean up ZFS information from the backup disk:
The first and last megabyte of the backup disk, which hold ZFS information (plus other stuff) are erased:
dd if=/dev/zero seek=<backup disk #blocks minus 2048> count=2048 of=/dev/rdsk/<backup disk>s2
dd if=/dev/zero count=2048 of=/dev/rdsk/<backup disk>s2
- Label and partition the backup disk in SMI :
format -e <backup disk>
     label
     0          -> SMI label
     y
     (If more questions asked: press Enter 3 times.)
     partition
     (Create a single parition, number 0, filling the whole disk)
     label
     0
     y
     quit
     quit
2. Data copy
- Create the target ZFS pool:
zpool create -f -o failmode=continue -R /mnt -m legacy rbackup <backup disk>s0
Note: the chosen pool name is here "rbackup".
- Create a snapshot of the source pool :
zfs snapshot -r rpool@today
- Copy the data :
zfs send -R rpool@today | zfs receive -F -d rbackup
- Remove the snapshot, plus its copy on the backup disk :
zfs destroy -r rbackup@today
zfs destroy -r rpool@today
3. Backup pool reconfiguration
- Edit the following files:
/mnt/etc/vfstab
/mnt/etc/power.conf
/mnt/etc/dumpadm.conf
In these files, replace the source pool name "rpool" with the backup pool name "rbackup".
- Remove the ZFS mount list:
rm /mnt/etc/zfs/zpool.cache
4. Making the backup disk bootable
- Note the name of the current boot filesystem:
df -k /
E.g.:
# df -k /
Filesystem kbytes used avail capacity Mounted on
rpool/ROOT/root 31457280 4726390 26646966 16% /
- Configure the boot filesystem on the backup pool:
zpool set bootfs=rbackup/ROOT/root rbackup
Note: "rbackup/ROOT/root" is derived from the main boot filesystem name "rpool/ROOT/root".
- Copy the ZFS boot block to the backup disk:
installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/<backup disk>s0
5. Cleaning up
- Detach the target pool:
zpool export rbackup
I hope this howto will be useful to those like me who need to change all their habits while migrating to ZFS.
Regards.

Black screen with "Insert boot disk"

Hi, there everyone!
So here's the epilogue to my story.
I wanted to install Windows 7 on my late 2011 MBP running Lion. Went to Bootcamp to get the process done, as I get there I see that I'm lacking the option to make a start up disk on a usb, so I looked up ways to change that. After many days of searching and trying I stumbled upon the option to change coding on the info.plist file inside the package contents of Bootcamp. When I was done changing a few things (as directed to online) Bootcamp then no longer would open, only bounce on the dock then close. I tried turning back the clock with Time Machine with no avail. I was left with an error built into the system, and thus forcing me to upgrade to Mavericks.
Now my current issue:
After upgrading, I once again tried to change BC to allow me to use a USB instead of a DVD to install Windows. Once again, desperately, I changed the info.plist in Bootcamp (leaving an original copy of the file, and changing the duplicate) in order to do so. This time with success!
After already having saved the "latest Windows support software from Apple" from when I was on Lion, I skipped this step and proceeded to transfer the .iso file I had to the usb thumb drive. Successful!
From there, I then went on to partition 35 GB of space on my HD to windows and just let the magic happen!
Only (this is were the real question comes in) when the system restarted, post-partition, I was left with (as the title says) the black screen with "No bootable device -- insert boot disk and press any key"
So my question is: Where is the "any" key???
Haha sorry about that, just had to!
But in all seriousness, I was left with the Boot screen and my usb drive sticking out of it containing the file needed to boot Windows 7.
I've tried everything I possibly could:
Restarting on mac, ejecting USB, then sticking it in when the boot screen comes up.
Putting the .iso on a DVD and trying it the original way.
Restarting with no DVD or USB in then placing them in after the boot screen.
Even restoring my partition, repartitioning the HD, and then re-installing the .iso file on the thumb drive once more all over again in an attempt to get it working.
All with no luck.
I've been scouring all over the internet looking for the solution for days to this problem before I took it upon myself to ask the community.
If anyone can offer any insight to what else is left for me to try with Bootcamp would be immensely, appreciated!
If worst comes to worst I may be forced to try Parallels or VMWare Fusion to get Windows 7 running on Mac, but I would much rather have Windows running independently on my Mac for games, rather than having a Virtual Machine slow down the gaming experience.
Thank you!
(P.S. And sorry about the length!)

So, I decided to restore my Mac into factory settings?
If you want to do that, you have to boot the Mac from your Mac OS X Install disc by inserting the disc, then restart while holding down the 'C' key until you see the Apple logo. Then you choose your language (English) and let the installer do it's thing.
To remove a CD that failed to eject, you startup the Mac while holding down the mouse button (trackpad button on a laptop) until the drive ejects.
So, I tried boot camp.
Don't do that. Boot Camp has nothing to do with this; it's for running Windows on your Mac.
I tried to press the on button, to try and force shut down - failed.
You have to hold it for about 6 seconds for it to shutdown. Did you do that?
I tried pressing the Option key, which I assume is the key with the alt on it, right??
Why would you need the Option key for this?

Neo4 K8N Plat SLI - Boot Disk Failure :(

Having installed Windows XP Proffesional, I installed the graphics card drivers and was asked if I wanted to restart. I went ahead and restarted, and was confronted with the "boot disk failure..." error message.
I eventually decided to reinstall Windows but when the "press any key to boot from CD" message came up, in an act of defiance, I decided that I wouldn't press any key at all.
I was suprised to see Windows load up.
Booting without the Windows CD in the drive results in the error. With the CD in the drive it boots - what could be causing this? The mobo, the HDs, the OS?

The Samsung ... yes, that's a sad story ...
I'm one of the people who believes that two disks in a SATA Raid don't nessecarely have to be the same brand. It even haves some pro's to not use the same types of disks, but that's another topic. They should, however, be the same size of course. I used one Samsung spinpoint (120GB) and a Western Digital Caviar (120GB) in a Raid-0 array. On the Dutch forum this array is known as "RAID-UI" . It worked pretty well, no crashes, pretty fast data transfers ... but then, one day, I had a hickup using Ghost. I saw: Creating image of C: 23% complete ... And it stood there for a very long time. After that, Ghost shut down giving an I/O error. I investigated the error and becam aware that there were disk errors on C: (one partition of two on the SATA RAID-UI). I had the whole lot repaired using CHKDSK and everything seemed OK again.
I looked in the VIA Raid tool and saw a difference in size between "capacity" and "real capacity" of about 0.064MB on the Samsung. Well, nothing to cry about yet. But I kept on getting disk errors and I kept on having to run CHKDSK. After a week I lost over 25MB and every day I lost more to bad clusters. Knowing that two striped disks have to be the same size, I started to wonder when this raid would crash. But, since I don't like the idea of suddenly loosing a 220GB disk array, I decided to throw out both the Samsung and the WD. (The WD is in another PC). I bought two Seagate disks and didn't go back to Samsung, because of the terrible answer I got from Samsung Holland.
I mailed them about the broken disk and asked for a replacement (disk is about 13 months old and there's a two year waranty). They simply refused to give me a replacement. They stated that I probably messed around with the disk, cause of the bad clusters. Stupid anser, to my opinion. The disk simply died from one day to the other.
Note that this disk has always hung right behind an inlet fan! So it never got hot.
I'm very happy with the seagates now. They're more quiet and ... FASTER! I get data-transfers of about 94-96MB/s, while with the other array the max was about 88MB/s.

HT1199 After trying to install window 7 my new iMac will not reboot back to apple. Black screen "No bootable device -- insert boot disk and press any key". How do I get out of this?

After trying to install Windows 7 in my new iMac It will not boot up back to Apple. I have a black screen with the following "No bootable device -- insert boot disk and press any key". My iMac did not come with a boot disk. What can I do?

Try holding down the option/alt key during a restart and see if you can see/select your boot drive there.

No bootable device - insert boot disk and press any key to continue

I accidentally turned off my mac book pro by keeping my finger on the Power button too long. When I tried to turn it on again, the computer didn't boot. Instead, I got the "No bootable device..." message. I was not trying to install anything. A moment before this happened, the computer worked perfectly. Any suggestions?

I'm lost. Why would my Mac try to boot into Windows? It hasn't even heard of Windows. Not a trace of it on my laptop. I tried holding down the Option key, but nothing happened. I tried a couple more options I read on the internet, but no success yet. Every post I saw involved problems where people tried to install Windows. I have not tried installing ANYTHING. It just quit on me and now I'm stuck. Not an Apple store nearby. And I don't think that my computer even came with a boot disk. Does it matter what kind of boot disk I use? Would a Windows disk work? Or do I have to use a Mac boot disk? I'm so sorry for being so stupid. I'm such a novice regarding these problems.

./setup_install_server failing with ZFS

I recently upgraded my jumpstart server to 10/08 with ZFS boot. My installation media is located under /export/install/media, where /export/install is a ZFS file system (zpool1/install).
I'm trying to add Solaris 9 installation media, but setup_install_client errors as follows:
2009-01-14 12:06:44 # ./setup_install_server /export/install/media/Solaris_9_905hw_sparc
ERROR: zpool1/install is not a local filesystem, cannot export /export/install/media/Solaris_9_905hw_sparc for install clients
2009-01-14 12:06:58 #I assume setup_install_client from older install media isn't smart enough to handle an underlying ZFS file system. Is there some way around this?

You could probably hack setup_install_server to not worry about that check. Or you could just copy of the image directory yourself to the correct location.

No boot disk detected or boot disk failed

I'm asking this for my father. He does not have the internet right now. Nothing to do with this issue though.
He has a Pavillion 23, model # 23-1270. A week ago he went to turn on his computer and got an error message saying, " No boot disk detected or boot disk failed. My sister called HP and one of the techs said it was the hard drive and it needed to be replaced. So it was replaced. Went to put Windows 8 back on from the disk, and it still pops up with "No boot disk detected or boot disk failed". My sister ran diagnostics on it and it comes back saying that the hard drive passed. But nothing about the dvd/cd player. Would it not pick that up? It is part of the computer. My question is: Now that the hard drive has passed, and its not reading the Windows 8 disk, is it a dvd/cd problem, or is it some thing totally different? My sister and my dad have money issues right now and can't afford to use an HP tech. So I'm hoping that someone knows what could be wrong and what I may be able to try.
Thank you so very much,
Andrea K.

Hello liv2lrn,
This is bad news especially around Christmas time. Your fathers computer is not worth fixing. Motherboard is corrupted, because these steps given faild. It is cheeper to buy another computer then it is replacing a motherboard. That's even if HP has one in stock. What I would do is shop on E-Bay you can find real good deals there for another good used one. I puchased a high value Sony VGC-LLT25E 24" screen computer for $300.00 Amazon at the time had two listed for $1999.00 and the other one at $1800.00 both were sold with in two weeks. I got lucky . That computer has out lasted three HP computers witch are newer. It is in mint condition runs a whole lot better then my HP's computers do. Shop wisely. You can save lots of money like I did.
Good Luck I am sure you can find a real good deal like I did.
frrw.

Boot from second hard drive with ZFS in Solaris 10 x86

Hi,
The usual menu.lst to boot Solaris10 x86 with a boot environment that contains a ZFS boot loader is this one
title Solaris 10 5/08 s10x_nbu6wos_nightly X86
findroot (pool_rpool,0,a)
kernel$ /platform/i86pc/multiboot -B $ZFS-BOOTFS
module /platform/i86pc/boot_archive
title Solaris failsafe
findroot (pool_rpool,0,a)
kernel /boot/multiboot kernel/unix -s    -B console=ttyb
module /boot/x86.miniroot-safeI understand that to add an alternate boot disk, I have to play with installgrub and then attach it in the pool.
But my question is : Is there a way to boot from my alternate hard disk by adding a new entry in menu.lst or is the only
way is to modify the BIOS parameter?
Thanks for your help,

But ok, I imagineI can add a grub entry. But what I want to know is what is the exact way to boot from an alternate hard disk on Solaris 10u6
x86.AFAIK there are only two ways to do this. Select the disks via BIOS which becomes a royal PITA in a short amount of time or play with a boot manager such as GRUB until you get the syntax right.
Personally I put all OS's on the primary disks if possible to avoid these situations and if I have others to play with then you can easily mount them in or set them up as D: drive etc...
The only exception would be in an enterprise setting where you need to do things such as mirroring but then again in those situations it's only one OS per machine anyways so it's much easier.
So at the end, I am not sure what I have to configure and what is the procedure to boot from my alternate boot diskTry the grub homepage for the grub manual and hopefully for a mailing list or try a search engine.
http://docs.sun.com/app/docs/doc/819-5461/zfsboot-1?a=view
has an example to follow of using -B.
And moreover, the installgrub does not working for me :

You shouldn't need to do an installgrub if you installed Solaris. Try c5t4d0s0 not s2.

Can't boot with zfs root - Solaris 10 u6

Having installed Solaris 10 u6 on one disk with native ufs and made this work by adding the the following entries
/etc/driver_aliases
glm pci1000,f
/etc/path_to_inst
<lang pci string for my scsi controller> glm
which are needed since the driver selected by default are the ncsr scsi controller driver that do not work in 64 bit.
Now I would like to create a new boot env. on a second disk on the same scsi controller, but use zfs instead.
Using Live Upgrade to create a new boot env on the second disk with zfs as file system worked fine.
But when trying to boot of it I get the following error
spa_import_rootpool: error 22
panic[cpu0]/thread=fffffffffbc26ba0: cannot mount root path /pci@0,0-pci1002,4384@14,4/pci1000@1000@5/sd@1,0:a
Well that's the same error I got with ufs before making the above mentioned changes /etc/driver_aliases and path_to_install
But that seems not to be enough when using zfs.
What am I missing ??

Hmm I dropped the live upgrade from ufs to zfs because I was not 100% sure it worked.
Then I did a reinstall selecting to use zfs during the install and made the changes to driver_aliases and path_to_inst before the 1'st reboot.
The system came up fine on the 1'st reboot and did use the glm scsi driver and running in 64bit.
But that was it. When the system then was rebooted (where it made a new boot-archive) it stopped working. Same error as before.
I have managed to get it to boot in 32bit mode but still the same error (thats independent of what scsi driver used.)
In all cases it does pop the SunOS Relase banner and it do load the driver (ncrs or glm) and detects the disks in the correct path and numbering.
But it fails to load the file system.
So basically the current status are no-go if you need to use the ncrs/glm scsi driver to access the disks with your zfs root pool.
File-Safe works and can mount the zfs root pool, but that's no fun as server OS :(

I booted with start up disk , ran disk repair and all is ok. Tried to re-install OS but when I get to designating drive its blank. When I go to startup disk there is a "?" mark. When I restart under startup disk search for a drive it still comes up with nothing. Before I got the grey spinning wheel I had a locked screen. Could not move curser or click on anything. Finally just shut down. Thank you in advance for any help!

Shouldn't still have a 'beachballing'... if the drive is being found and the system is trying to boot from it but is having problems, I would suggest looking over ds store's user tip - Step by step to fix your Mac.
It's likely either something corrupt in your system files or a failing hard drive. But follow ds's steps until you find the cause of the problem.
Good luck,

My G5 won't boot up. The Gray screen comes on and it thinks about it until the fan revs up like it is about to explode. A friend said to start it up with the OS disk and then go to utilities. Didin't work. Any suggestions? Isn't there a key stroke to help

Oh, so this is where I ask my question. Sorry, first time here. As I was saying in my long intro, the gray screen come up and the thing is spinning at the bottom, but nothing happens. Then the fan starts reving up like it is about to explode and I have to manually shut it off. A friend told me to start it up with the OS disk and then go to utilities. I couldn't find the thing, so I went out and bought another. Needless to say, it didn't work. Is there a key stroke to help jump start the machine? How can I get into this thing? I would prefer not to take it in because there are a lot of things on there I don't want just anyone to have access to.Thanks, in advance, for your help!

The last time you had to hold down cmd opt pr more than twice was a decade ago....
G5? PowerPC? 10.5? or earlier....

Your drive does need to be repaired, and best things to buy are another backup recovery drive, with a small OS X partition; a copy of Disk Warrior is expensive @ $90 but excellent and best.
Never bother with or use the drive or reinstall while there are errors. Don't take a "clean' bill from Apple Disk Utility to mean there are no errors. Only that it didn't find what it looked for.

Make sure to have multiple backup sets and of your system so if there is a serious problem, you can just erase and restore to be back runninig.
Sounds like your G5 though needs PMU reset, not PRAM, and the best way for those is to clear nvram instead. might even want to check for dust; tell what System Profile says (later) as to "PowerMacX,Y" or "MacProX,1"

The Utility menu is on the menu bar of an "OS X Install DVD" and at the point where you get to but stop at "install....' for OS X. you probably do need to install OS X on another drive to work from.
Oh, a real severe issue and damage to the drive directory or filesystem CAN in cases prevent booting from DVD (the system still tries to find and see what boot volumes are present) and can help to pull or disconnect the drive. Putting a drive in a FW case to turn on after startup is very useful.

Problems with Bootcamp Assistant: no bootable device -- insert boot disk and press any key

Hello Guys,
I got a problem setting up Windows 7 on my recently bought 13" MacBook Pro (2,3Ghz Core i5).
I used the bootcamp assistent to create a partition of 50GB on my Mac, everything is fine until now. I insert the Windows 7 disk and follow the instructions. But when I restart in spite of starting the installation of Windows 7, a black screen appears with a note saying "no bootable device -- insert boot disk and press any key". To exit this screen I then have to restart my Computer again, holding down the alt-key. In the following window I can just chose my Mac-Harddrive to boot from, the partition is not shown.
I used the software actualization tool to update to version 10.6.7 which is the most recent one i think.
The Windows 7 CD I use is actually a burned one. My University is a member of the msdn academic alliance and therefore offers me to download microsoft software for my work. I stress out that this is absolutly legal, I will only be allowed to use the software unitl I finished my studyings.
So as I said, I downloaded the Version of Windows 7 Professional with Service Pack 1 (x64) on my computer and then burned on a DVD. I want to add, that the file I downloaded turned out to be an iso file. At first, I just burned this file on a DVD but since it turned out that i got the above mentioned message, I burned a second DVD with the actual files of the iso (with foldernames like autorun.inf, boot, bootmgr, bootmgr.efi, efi, setup.exe, sources support, and upgrade)
I dont know if these details are of any relevance, but i guess it may be useful since I believe that the burning thing could cause the problems.
I have already browsed the Forum for quite some time now, but I didnt find a case with the exact same problem that I have, so I decided to rather ask you for help now instead of killing my brain like I did before (and I dont really have a clue neither of Macbooks nor of Windows-Computers, its always try and error for me)
I hope somebody can come up with some helpful ideas or a solution.
If you need further details on my system or anything, please feel free to ask
Thank you very much,
David

The Windows 7 CD I use is actually a burned one. My University is a member of the msdn academic alliance and therefore offers me to download microsoft software for my work. I stress out that this is absolutly legal, I will only be allowed to use the software unitl I finished my studyings.
Apple Disk Utility won't do a proper job and won't work (and it varies, some can start the install but fails later) Has to be burned at 2X Reduced Burn Speed

Help with "No bootable Device -- Insert boot disk and press any key" problem

Alright, I am on an Early 2011 17inch macbook pro. I have removed the superdrive to install a secondary disk drive for mass storage, then replaced the original one with an SSD blah blah blah. I do everything from the books, run bootcamp, make my USB windows 7 bootable in Bootcamp, go through everything and allocate 65gb towards windows. I have tried 4 different USB sticks and 3 different ISOs. Every time I try it, I get the same "No bootable device -- insert boot disk and press any key". I then have to hold down the power button, then restart, hold down option/alt key, and boot regularly into mac. I also read that holding option/alt whilst starting the macbook pro will show the windows USB stick, well it never appears. I dont know what I need to do, what I am doing wrong, but nothing is working. I guess the last thing I have to try is buying a superdrive and burning ISO to disc then try that. But I dont want to go out and spend more money. Other people have gotten it to work just fine from USB, I dont know what I must do or what I am doing wrong...
Open to suggestions and in desperate need of help. Anything is appreciated.
Thanks!

How to make boot disk for MacBook Pro with Mavericks pre-installed

Hi -
I recently bought a new 15" MacBook Pro with Retina Display, which came pre-installed with Mavericks (10.9.0). I want to make a bootable USB disk of the system software, and have successfly used DiskMaker X (formerly Lion DiskMaker) to make the USB boot disks for Lion and Mountain Lion. In those cases, however, I was running earlier versions of the OSX, and downloaded the new OSX version -- Lion and Mountain Lion -- from the App Store in order to make to make the disk. In this case, however, Mavericks was pre-installed, and I was unable to download it from the App Store (an alert said that it couldn't be installed on this computer... presumably because it was already installed). I would apprecite any suggestions as to how I can create the boot disk without the ability to download Mavericks. Thanks very much for any help anyone can provide.

Open App Store and locate the full installer download file (5.29 GBs) for 10.9.1. Download to your computer.
Make Your Own Mavericks, Mountain/Lion Installer
After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Mavericks flash drive installer using the Mavericks tool:
You can also create a Mavericks flash drive installer via the Terminal. Mavericks has its own built-in installer maker you use via the Terminal:
You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this command line after the prompt in the Terminal's window:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.
Wait for the process to complete which will take quite some time.
