Invalid bs_jmpboot in boot block

Hi I'm riiiic a new mac user
After a year of discussion, my brother conviced me to but a MacBook Pro 13" and here I am
The notebook (hardaware) is beautiful, superb, marvellous but the software part makes me unhappy.
Hundred of people told me, forgot any error message using a mac, and here we are:
This is an errore message from disk utility:
Verifying volume “disk0s3”
** /dev/disk0s3
Invalid BS_jmpBoot in boot block: 616e67
Errore: this disk must be repaired
Verify e repair volume “disk0s3”
** /dev/disk0s3
Invalid BS_jmpBoot in boot block: 616e67
Disk utility is unable to repair the disk....
How did I get this error ?!?! Like thounsand of new MAC users I got this error trying install win7-64 bit on the boot camp partition.
I'll now describe my movements:
- 1. creationof a partition using boot camp
- 2. installation of WIN7 64bit
- 3. unable to detect the win partition on finder.
- 4. boot with pressed alt and selected to boot from windows, anything was great, windows work perfectly (with boot camp drivers) and I'm able to detect and read files from macHD.
- 5. trayed to find a solution and installed MACfuse e NTFS-3G (it didn't work)
- 6. opened disk utility and found that "disk0s3" was unmounted and un reperable, the same disk from who I can perfectly boot win7.
Does anyone know how to fix the unbelievable error?
Thank u
ric

I have exactly the same problem. Although I can boot into windows 7 bootcamp partition, I cannot mount this partition on the mac os X. Have you found any solution yet?

Invalid BS_jmpBoot

I installed Windows 7 64bit on my iMac running the latest Snow Leopard release.
Everything worked find... I set up Windows how I wanted it but when it was time again to switch back to Snow Leopard I find that my iMac no longer recognized it.
I launched disk utility via the Snow Leopard install DVD and I could not mount my Mac partition... this was the error when trying to repair it:
invalid BS_jmpBoot
I don't know what to do. Through Windows I can still read the partition but the Mac can't boot from it.
Anyone have any explanation for this?
I've had Windows 7 installed via Bootcamp before and never experienced this problem.

I fixed the problem myself by using TestDisk on the SystemRescueCD.
Simply followed the instructions on how to use TestDisk on the TestDisk website and it was fixed in a couple of minutes.
What caused this problem is the Windows Disk Management utility. I didn't want my Mac partition to show up under Windows so I removed its drive letter to basically hide it from view. Unfortunately this messed it up so it could no longer be booted.
I've seen that some people have a similar error not necessarily due to what I did but perhaps my solution will work for those others as well.

Installed the latest Java update today on my older iMac and now it won't boot up at all. 2007 model worked fine this morning, now disk first aid say boot blocks f'ed.

I am using an older mid 2007 imac 24 inch running snow leopard 10.6.8
I normally accept software update recs, and today when installing the security update to java, all went fine till restart, when I got the universal "NO" sign, the circle with the line through it and just spinning gray bars underneath.
Booted from system disks, ran first aid, said the boot block partitions or something like that needed updating but disk appears to be ok. Still not working.
Do you think Alsoft Disk Warrior will fix? I am running off external back up drive now.
Thanks for any help or advice. Apple as usual is as useless as tits on a bull, or a screen door on a submarine, pick your simile...

If your backup's up to date it might be less hassle to erase the internal and clone back from the backup. Don't allow the update next time it appears - you're not the only one having problems it would seem.
Note; the message "updating boot partitions" is a standard message that appears after a repair run. It won't go away and should be ignored.
Provided the message "The volume Macintosh HD Seems to be OK" in green has appeared, your disc fle system is fine.

Solaris 8 boot block

I have a Solaris 8 machine that was having a hard drive issue. I shut the system down and then it will not boot.
I booted off a CD and ran fsck /dev/rdsk/c0t0d0s0 and it came back with a superblock error and I typed yes to fix it. I then tried to boot again and it still would not boot.
I then tried to reinstall the boot block but that did not seem to help. # installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s0
Where is the boot block suppose to go? Does it always go on slice 0 of the boot drive or does it go where the root partition is located. The root partition is actually on slice 4 c0t0d0s4.
# df -k | grep dev
/dev/dsk/c0t0d0s4 8256660 3799018 4375076 47% /
I have been fighting this issue all day. I am almost to the point of restoring the whole system. Thanks in advance.

When I do a printenv boot-device I get boot device = disk:b. What does disk:b refer to? You system is set to boot from Slice #1 of whatever your system's hardware defaults to for the first disk location.
If you were seeing "disk:a" then it would refer to the zero slice of the drive (S0).
If you saw "disk:c" then it would boot from the third slice (S3).
Perhaps the following two old OBP reference manuals can be of help.

Could not read boot block (input/output errror) powerbook g4

Hello
My friend gave me a powerbook g4 and a copy of osx lion, I would like to install it but the internal hardive is not available within the "select Destination" area of the installation process. I tried to repair the disk which is labelled Disk0s1, but shortly after it is underway i recieve this message.
**/dev/disk0s1 could not read boot block (input/output error) Error: The underlying task reported failure on exit. 1 non HFS volume checked, 1 volume could not be repaired because of an error.
Within disk utilities the Disk01s is grey, I can try to repair it but the above error occurs. Do you know what the problem is and how I can fix it?

Since you are going to install system fresh, it sounds like, you should erase the drive. Boot from the installer disc, then select the language but do not start the installer. From the menu bar, you should have either an Applications or an Installer menu. From one of the menus, you can then start Disk Utility.
From the drives and volumes pane, select the internal drive hardware listing.
This will now allow you to partition or erase the disc. Now click the Erase tab and select Mac OS Extended (Journaled) as the format and then click the "Erase" button. You can name the volume that will actually be created, like for instance "MacintoshHD" or whatever you want.)
Once the erase has completed, you need to check the information for the hard drive at the bottom of the window. Be sure that the partition scheme is Apple Partition Map. If for some reason it is something else, like GUID, you won't be able to install MacOS on it. You will need to click the Partition tab, click the "Options..." button and select Apple Partition Map, then click the "Partition" button.
Once this is done, then you can quit Disk Utility and you should be able to install Tiger on that HD.

Invalid command in boot strap mode

Hi All,
I am trying to install peoplesoft HRMS 9.1 with PT 8.51.
Firstly I encountered problems running grant.sql ,it showed that PSSTATUS, PSOPRDEFN, PSACCESSPRFL TABLE OR VIEW does not exist.(So i tried following "Using Data Mover, You can login in to the SYSTEM schema and EXPORT those tables (Using the 'EXPORT <RECORD>' instead of 'EXPORT *'). Then using Data Mover again, login to the SYSADM schema and IMPORT the data. NOTE: You will need two DMS scripts, one to export and one to import, as well as making sure you're using the right USER/PW combination" solution).
Secondly I can login to DATA MOVER using three combination of id's and psswds i.e system/oracle(original bootstrap mode id's) and PS/PS, SYSADM/SYSADM but the last two combinations also shows as bootstrap mode inside datamover.
Lastly i triesd to import the three tables from one schema to other by logging in to system/oracle as all three tables are present under this schema but when i run,
set log C:\REF0001_EXPORT.log;
set output C:\REF0001.dat;
export PSSTATUS;
It shows the below error in logs,
Invalid command in boot strap mode
Ended: Tue Jun 14 00:37:12 2011
Unsuccessful completion
Pls help!

Thanks Nicolas,
So now what do you advise me to do...Do i need to start a fresh from scratch??..I beleive half of the tables present r under SYSADM and rest half under SYSTEM..So is there anything which i can do to import those??

Zfs boot block size and ufs boot block size

Hi,
In Solaris UFS file system , boot block resides in 1 to 15 sectors, and each sector is 512 bytes total makes 7680 bytes

/usr/platform/SUNW,SPARC-Enterprise-T5220/lib/fs/ufs
bash-3.2# ls -ltr
total 16
-r--r--r-- 1 root sys 7680 Sep 21 2008 bootblk
for zfs file system the boot block size is

when we install zfs bootblk on disk using the install boot command ,how many sectors it will use to write the bootblk?
Thanks,
SriKanth Muvva

Thanks for your reply.
my query is when zfs boot block size is 16K, and on disk 1 to 15 sectors(here boot block going to be installed) make around 8K,
it mean in the 16K,it writes only 8K on the disk
if you don't mid will you please explain me in depth
I m referring the doc for UFS, page no 108 ,kernel bootstrap and initialization (its old and its for Solaris 8)
http://books.google.co.in/books?id=r_cecYD4AKkC&printsec=frontcover&source=gbs_ge_summary_r&cad=0#v=onepage&q&f=false
please help me to find a doc for kernel bootstrap and initialization for Solaris 10 with zfs and boot archive
Thanks in advance .

Bad sector in Boot block

Solaris 8 on a sparcstation 20 to an external disk drive bay
This system was installed and working. I needed to do a fresh install and I started having problems. The install appearrs to work fine. It get s to the point of reboot. Then it fails to come up with an error or Can't find boot sector in boot block.
Any ideas what might be going on? Or what I might do to get this fixed and get my system installed and running again?
I have verified that the disk is fine and has no hardware problems. This has been installed 2 times before and I never saw this issue.

You can try either running a disk check through Windows and setting it to automatically fix errors (which will mark bad sectors) or you can try reformatting the iPod disk (a full format, not quick). A full format should also mark bad sectors. Once a sector is marked "bad" no data will be written to it.

Installed an SSD in place of hard drive, DU reports that there is an invalid number of allocation blocks.

I recently installed a Mercury Extreme Pro SSD in my laptop in place of the hard drive. I used Carbon Copy Cloner to make the SSD a bootable disk and transfer all my files. Today (about a month later) while checking the old HD (now in an external case), I decided to run "Verify Disk" on the new SSD. When I run it on the disk volume, Disk Utility reports that there is an invalid number of allocation blocks - much to my surprise. When I run it on the drive itself there are no errors.
The new disk works fine as the startup drive. What's the meaning of the error and how do I fix it?

No, on both counts. FW800 will not support the speed of SSDs. It barely supports the speed of very fast hard drives. But it beats USB 2.0.

Boot block recovery

Hello,
Well, this one isn't as desperate as my last post. Basically, I need to know where to go to get a boot block recovery cd. Is it downloadable from here? If so, where? Otherwise, how else do I get one? How do I get a backup disk in case this happens again?

hello
i can lead you to the correct download section if you could provide your model number for your BIOS update

Usbmultitouch debug report id is invalid when i boot in single user mode

been having a problem for a few months where my track pad will not work at all when i start my mac.
the only things that have worked so far to solve the issue is to restart the laptop, or on occasion to put the laptop to sleep and wake it up several times.
booted in to sigle verbose mode and see the message
AppleUSBMultitouchDebug: ReportID is invalid in AppleUSBMultitouchDriver::_deviceGetReportWithLookup
AppleUSBMultitouchDebug: ReportID is invalid in AppleUSBMultitouchDriver::_deviceGetReportWithLookup

Looked around and have found no help anywhere so far.

I think it would be worth a try to repair permissions and then boot from the Install disk to run Repair Disk in Disk Utilities. If you still cannot boot into single user mode after that, perhaps obtaining and running Disk Warrior can resolve the problem.

Invalid Keys Response (Boot Camp)

Hi,
I run Boot Camp (Windows 7 Ultimate) on iMac and have no issue with the keyboard thus far but notice that the at-key ("@") is inter-changed with another key and backward-slash key ("\") is now hex-key ("#") and I can't find it and trying out all the keys.
I went back to Mac and run boot camp to download the latest driver, went back to Windows and did a repair but the result is the same.
What I notice is :
#     -     become "pound sign"
@     -     become " (double quotes)
\     -     become #
|     -     become ~
"     -      become @
Tried trobleshooting on the regional and language settings but it does not help either.

Tried the BC update (v2.1). Still exactly the same. No volume keys, no eject key. no brightness keys, no nothing!
Plus Windows says my iSight is unprogrammed and detects IR receiver at every boot, but fails to install drivers for it. Whatta bummer.

Satellite A300 : cannot boot : blocked by Phoenix TrustedCore Setup Utility

This one is a bit bizarre. We have a Tosh Satellite A300-193 Laptop (Manufacturer Code: PSAJ1E-01000XEN) purchased July 2008, which my daughter uses for work. We have Kaspersky anti-virus on it, but since its license had expired (and we didn't really like it), I was going to remove it and install Avast.
Kasperky's removal instructions involve getting their "kavremove" tool which their instructions say should be run from safe mode. So, having downloaded the tool, I pressed F8 to boot to safe mode. ...
That's when things went wrong. Instead of the typical black boot-options screen, I got a password request from "Phoenix TrustedCore Setup Utility". We have never set up a password on this machine, and I have never seen this particular screen before. After three wrong guesses (!), the machine powers off.
Now when I turn it on, it goes straight to this Phoenix password request: I don't touch F2, F12, F8, or anything. I cannot work out why it should do this, nor how I can possibly by-pass it. None of my password guesses work (of course). My daughter is a primary school teacher with a school inspection looming in a week: while she has most of her work on a USB stick, there is data on this machine she really needs. Needless to say, tensions are rising.
I have googled all evening, so I know there is no point asking about passwords. But can anyone point me in a helpful direction? I'm baffled and at a loss. Grateful for any help (or hope!).
David.

Hi,
Which steps/procedure in that other thread you linked did you do to make it boot without asking for the BIOS password?
I looked through that message briefly, and what I didn't see is that after you get it to boot, you should probably go into the BIOS and reset the BIOS settings to default.
Another possibility is that the BIOS firmware itself may be corrupted, causing it to think that there's a BIOS password set. If that's the case, you may need to try to flash the BIOS with a known good BIOS, maybe booting from floppy or CD to do the BIOS flash.

I can't boot to Windows after resizing my Mac partition.

So, I recently decided to resize my bootcamp Win7 partition. This is something I have done successfully before, by:
1) Booting into Macintosh
2) Using Disk Utility to decrease the size of the Mac partition (20GB the first time)
3) Booting into Windows
4) Using Mini-Tool Partition Wizard (third-party) to allocate the free space to the Bootcamp partition.
There were a couple issues caused by this the first time around, mainly the fact that Macintosh didn’t recognize the fact that the free space had been taken, and had trouble reading from the Windows partition. However, I could live with that. I have since rebooted to both Mac and Windows several times without problem.
Recently, I decided I needed a bit more space, and so started to follow the above steps, shrinking the Mac partition an additional 15GB. Only when I went to reboot to reallocate the space, the Windows partition didn’t show up as a bootable option. Confused, I booted back to Mac, and the Bootcamp partition was still there, but renamed “disk0s4”, and unmounted. Reparing the disk failed (“Invalid BS_jmpBoot in boot block: 15921e”). The disk wouldn’t mount (not even sure if it was supposed to be mounted earlier, but that’s what it looks like). It also appears grayed-out in the list of drives to the left. It looks like I can create a dmg from the windows drive, although I haven’t done that yet (I will soon).
Any solutions for this? Although I will erase the drive if absolutely necessary, it would be preferred if that wasn’t the first option to try. I had no problems like this the first time I resized the disk.
(My mac partition is running Mavericks, if that is of any relevance)

Can not boot into OSX after boot camp installation and resizing of Macintosh HD

So from the beginning what I was trying to do was set up my iMac (27-inch, Late 2013) with boot camp so that I could play some old windows based games that can not be played in Parallels.
I went through the Boot camp process and everything set up just fine.
I had both OS X Yosemite 10.10.2 and Windows 8 Professional running but as I was installing games on to boot camp I discovered I did not allocate enough space and needed to extend the Boot Camp partition.
I used boot camp utility to set OS X as the default start up disk and had it restart
I launched into OS X and used Disk Utility to shrink Macintosh HD another 120GB
Restarted again holding option and launched into Windows
Used the disk management in windows to try and extend the boot camp partition into the unallocated space.
It was not an option to extend it so I tried to create a new simple volume from the unallocated space then delete it and try to extend it again.
It still was not an option.
From there I went to restart again while holding option and the only options I had were 10.10 Recovery and Windows
I tried using disk utility in recovery and Macintosh hd now only showed disk0s2
I tried to verify and it could not verify
I tried to repair and it could not repair.
I put the iMac in target disk mode and using a thunderbolt cable I tried using disk utility from my MacBook Pro (13-inch Mid 2012)
Verifying volume “disk2s2”Verifying file system.** /dev/rdisk2s2

File system check exit code is 8.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
This is the same error I got on my iMac
I used terminal diskutil list and got:

   4:       Microsoft Basic Data BOOTCAMP                70.3 GB    disk2s4
I can see that Macintosh HD was disk2s2 but it now shows its Microsoft Basic Data.
I did not format this partition and it was working fine till I restarted the computer after resizing Macintosh HD.
I am not sure what I can do to fix this.
I've found multiple articles about similar issues, but the issue thet they have was that they could not boot to Windows instead of my issue not booting to OS X

****************    Update    *****************
From the Windows Partition using Disk Management I can see that the drive is still labeled Macintosh HD and that all of my data is there.
I have a complete backup so i'm not worried so much about the data.
What I'm most interested in is trying to solve this issue because I'd like to continue using boot camp and I actually work with mac computers and would like to be able to help others if this issue arrises again.
