Urgent need help: I run windows 10 on iMac. I can't boot into Windows 10 after update to El Capitan 10.11.5. Help, please!

An urgent need to help!

I've been running Windows 10 on my iMac via Boot Camp. I just upgraded to El Capitan 10.11 to 10.11.5. I don't know if it was because of this upgrade that made me not be able to return to Windows. In the windows startup disk, my windows HD and OS X HD icons are all grayed out. So, I can't select which one to be my default startup Mode of the disc. Help, please!

Unlock you the boot floppies pane by clicking the lock button? Look at the lower left corner of this screen.

    Hi Experts,

    We urgently need a help from you all, Apologise for posting this simple question, but left with no option.

    Can you please let us know if there is a quick way through query DB or the java code to find duplicated in IOM user accounts. We urgently need the data as we have it
    to update our client and perform a cleanup.

    We use IOM 9.1.0.1 and there are several user accounts created for the same as users e-mail addresses even tag multiple accounts of users etc.

    We have assigned unique employee id, but do not know if it is updated for all users.

    Pulling the full report in table USR DB Extract all records, but you are looking for a good method... like the questioning of users with the same Fname, name etc... Please
    Let me know as soon as possible.

    Concerning
    SS

    Really depends on what you have for unique identifiers... If you want just a report of all users with the same name and first name:

    select * from usr a join
    (select usr_first_name, usr_last_name from usr
     group by usr_first_name, usr_last_name having count(*) > 1
    ) b on b.usr_first_name = a.usr_first_name and b.usr_last_name = a.usr_last_name
    order by a.usr_first_name, a.usr_last_name;
    
  • SOME URGENT NEED HELP PLEASE blackBerry smartphones

    HEY!

    How to block a number or a number private call me again?

    I can delete all the call connect together, not one by one?

    Thank you!

    Call blocking is a feature offered by your operator, usually at a cost. Contact them for more information.
    To remove all entries from the call at a time, press the green phone button to open your app phone. Then, click the phone tab, which shows the phone with two arrows. If you have a phone with a physical keyboard, press and hold the "A" button you press to make capital and scroll through the numbers until they turn blue. Then, press the menu key and select Remove. If your phone has a touch screen, I don't know the method.

    I hope that helps you.

    If you replace code valid, clean and well with a useless

  • I have 2 problems-how can I activate my Add ons and how to uninstall Windows Anti Virus. I need help, please.

    I have Windows XP 32-bit with IE8 Add ons.  I mainly use Firefox Mozilla for my browser and Yahoo as my home page.  Anyway, I have tried all the support and help guide and technicians told me to do to get add ons to open and activate but in vain.  This computer was given to me as a profession, and it was used in a Bank, so I think that the system administrator has disabled the add ons.  I myself as an administrator and use the tips and tricks given windows and Microsoft, but I always run up a wall.  I need help, please.
    I also need to know how to uninstall Windows antivirus software.  I can't find anywhere on my computer.  I feel really stupid and he is probably right in front of my face, but I can't find it to uninstall.  I have McAfee that I paid dearly for if I want to use it until it expires.

    This "Microsoft antivirus' witness (AKA Trojan W32/FakeAlert) hijackware infection!

    If you manage to somehow move to Win7, you will always have an infected computer.

    The ONLY way to solve the problem is by formatting the current hard drive and do a clean installation of Windows, whether it is WinXP or Win7.

    The ONLY way you can do a clean install of Windows XP if you have disks that came with the computer or if by chance, there is a hidden partition restore (not to be confused with the system restore).

    If your kids er - well & their spouses are going to spend money on a new HARD drive, they'be be better spend on a low-end Windows 7 computer and brand-new (for example, a netbook or a mini).

    NB: Any data on your Windows XP computer must be considered 100% reliable! (This includes all of your usernames and passwords, for example, those used for online banking, etc.) You do NOT want to put ALL the data from Windows XP to a new computer or HARD disk.

    Good luck, Grandma. Hope that your grandchildren will treat you better than their parents.

  • Cannot run Windows 7 after installing Windows XP.

    Hi all, I have a problem with my windows system. I've been a happy user of Windows 7 Professional, but I missed my old XP, then I installed it, and... I can't run Windows 7 now. I can't choose the OS I want to use, but Windows XP runs as all other systems were not. You know, where is the problem? Need help please, if you can.

    Thanks for all the help.

    If you overwrite your Windows 7 partition in the process and you have valid licenses for both systems, then you can try to change the Windows XP boot manager to restore the Windows 7 operating system:

    http://support.Microsoft.com/kb/306559/en-us

    The article is a bit old, but its principles will probably still allow you to dual boot Windows 7 and XP provided you delete the Windows 7 partition when you reinstalled XP.

    While the dual-boot will probably work for you, I think it would be better for you to perform a Windows Anytime Upgrade to Windows 7 Pro or above and then use the XP compatibility mode:
